Air date: Sep 8, 1966

The Starship Enterprise makes a routine call at the arid, uninhabited planet M-113 in order for Dr. McCoy (DeForest Kelley) to give a required annual medical check-up of the husband-and-wife team of archeologists working there. One seemingly minor complication is that Nancy Crater (Jeanne Bal), the wife, was once involved romantically with McCoy. Captain Kirk and Dr. McCoy meet with an irrationally hostile reception from Robert Crater (Alfred Ryder), however, and then members of the crew start turning up dead from unknown causes. Ultimately, it's determined that they were killed by a sudden and medically inexplicable loss of all the salt from their bodies. The mystery deepens as some crew members find themselves approached by mysteriously compelling strangers, and the planet below is short one of its two inhabitants. Eventually, Kirk and Spock determine that their adversary is the last native inhabitant of the planet, a kind of salt "vampire" that has the ability to alter its appearance to the shape of whoever its victim most wants to see. Needless to say, finding the vampire aboard the ship is easier said than done. Its shape-shifting ability has also allowed it to temporarily incapacitate McCoy, whose ignorance of events nearly costs Kirk his life.

While on a routine journey to a local Starbase, the starship Enterprise receives orders to transport a special passenger, a young boy known only as Charlie X, in this episode from the first season of the landmark science fiction series. An orphan with an abnormally high intelligence, Charlie claims to have been raised entirely by computers in an isolated, automated outpost. Yeoman Janice Rand takes a particular interest in befriending the strange boy, and he responds, developing a romantic attachment to the woman. When Rand gently dismisses his affections as puppy love, however, Charlie's love quickly turns to rage. The boy begins to unleash highly destructive mental powers, which he had previously hidden, against all who he feels have slighted him, and Captain Kirk must find a way to stop the child before he and the Enterprise are destroyed.

The series' second pilot episode (following the then-unaired "The Cage") is an extraordinary science fiction-adventure for its time. The starship Enterprise, commanded by Capt. James Kirk (William Shatner), is about to probe outside of the galaxy when they encounter an old-style disaster buoy from a spaceship listed as missing for two centuries. Examining its memory banks, they find that the ship encountered an unknown form of energy at the galaxy's edge, which precipitated a frantic search for information in their computer about paranormal mental powers and the captain's ordering of the destruction of his own vessel. The Enterprise proceeds on course and hits the same energy barrier, escaping with its main drive disabled, nine crewmen dead, and First Officer Gary Mitchell (Gary Lockwood) mutating as a result of contact with the barrier. With the ship now years from any Federation base as a result of its disabled drive, the crew finds itself with a monster aboard. Mitchell quickly manifests extraordinary mental powers and an increasing contempt for the crew around him. Science Officer Spock (Leonard Nimoy) warns that Mitchell will soon be a threat to all of them, while psychiatrist Elizabeth Dehner (Sally Kellerman), who is in love with him (and, as later revealed, is also mutating from the energy blast), defends Mitchell as a potentially improved, evolved version of humanity. Kirk at first cannot face the choice that he knows he must make, of leaving his oldest friend marooned on an uninhabited planet that may also have the facilities to repair the main engines. Finally, Mitchell forces his decision when he turns on Kirk and the crew with mental powers they can't combat.

The starship Enterprise arrives in orbit around a planet on the verge of collapse and finds the survey team working there dead, all seemingly having gone mad. Unbeknownst to anyone at the time, one member of the crew brings the cause of the insanity back aboard the starship with him. It spreads gradually, bringing hidden personality traits of its victims to the surface -- one man literally dies of a suicidal depression, while Sulu (George Takei) assumes the role of an 18th century swashbuckler, and Lt. Riley (Bruce Hyde) thinks himself the captain, locking himself in engineering and shutting down the Enterprise's engines, just as the planet begins its final destruction and starts pulling the ship out of orbit. Kirk and Spock both contract the disease and must wrestle with their personal demons, as they face the seemingly impossible task of restarting the ship's matter/anti-matter drive with only minutes before the Enterprise burns up in the atmosphere.

Thanks to a freak accident involving the Enterprise's transporter device, Captain Kirk is split into two separate bodies, each with its own personality, in this installment of the popular television series. The two Kirks represent opposite aspects of the Captain's personality: one who is aggressive, forceful, and callous, the other caring, sympathetic, but also indecisive and weak. The two men vie for control of the ship, leaving the Enterprise without a definite commander. Meanwhile, the rest of the landing party, led by Sulu, remains stranded on the planet's surface until the transporter can be repaired. Spock, Scotty, and the others must find a way to reunite the halves of Kirk's personality and rescue the others before nightfall arrives, bringing with it extreme cold that could mean the landing party's death.

The crew of the Enterprise encounter unexpected trouble when they help retrieve a stolen Federation ship in this early episode of the landmark science fiction series. The theft turns out to have perpetrated by notorious con man Harry Mudd, who is traveling with a new set of accomplices: three astonishingly gorgeous women. These sirens entrance the male members of the Enterprise crew, allowing them to successfully steal several dilithium crystals, crucial elements of the ship's power supply. Mudd plans to use the crystals as leverage to bargain with the Enterprise, but Captain Kirk has his own plans -- as do, it turns out, Mudd's women.

The Enterprise must thwart a mad scientist who plans to exterminate the human race and replace them with androids in this episode from the first season of the landmark science fiction series. Captain Kirk discovers the plans of the brilliant Dr. Korby while accompanying the Enterprise's Nurse Chapel, who is also Korby's fiancee, on a visit to his remote laboratory. Kirk and Chapel discover that the scientist has been much changed by his recent discovery of alien technology which has allowed the creation of ideal, human-like androids -- including a stunningly attractive female android with whom he seems particularly close. The death of an Enterprise crew member forces Kirk and Chapel to realize that Korby's research has crossed the line into irrational obsession and that they must stop him before they become the next victims.

Exploring the remnants of a plague-ravaged planet, Captain Kirk and an Enterprise landing party unexpectedly discover a number of young children who have survived the otherwise total devastation in this episode of the original Star Trek television series. These children all possess a strong distrust of adults, with the exception of Miri, a young girl who befriends the adults and develops a youthful crush on Kirk. The reason behind the children's animosity becomes clear when the Enterprise crew members discover that they have also been affected by the plague, which prolongs childhood to hundreds of years but brings death to anyone past puberty. Indeed, Kirk himself has contracted the disease and must somehow find a cure -- a quest that becomes all the more difficult when he and Miri, who has also begun to show symptoms, are held captive by a violent gang of children.

While on a routine stop at Tantalus, a rehabilitation facility -- the twenty-third century equivalent of a hospital for the criminally insane -- the starship Enterprise is involved in an unsuccessful escape attempt. Captain Kirk (William Shatner) knows of the sterling reputation of Tantalus under its enlightened director, Dr. Tristan Adams (James Gregory), but he is compelled to investigate, due in part to the concerns of chief medical officer McCoy (DeForest Kelley) over the fragile mental condition of the would-be escapee, Simon Van Gelder (Morgan Woodward) -- and to the fact that Van Gelder is not an inmate at Tantalus, but was assigned there as Adams' assistant. While McCoy tries to help Van Gelder, with some assistance from Spock (Leonard Nimoy) and his Vulcan mind-meld (the first time this is seen in the series), Kirk and a psychiatric expert, Dr. Noelle (Marianna Hill), beam down to the colony. They discover that Adams has been experimenting with a very powerful and dangerous device, the neural neutralizer, using it on staff members as well as inmates to control their thoughts and psyches -- and won't tolerate any interference or inquiries from Kirk or anyone else.

The starship Enterprise encounters a menacing, enigmatic alien called Balok in this installment of the popular science fiction series. After finding the Enterprise's movements blocked by a strange, cube-like device, Captain Kirk orders an attack on the object. At this point, the towering, powerful figure of Balok appears, threatening to destroy the Enterprise. Kirk responds with a risky maneuver involving an obscure mineral known as "corbomite," hoping to outwit the alien. However, there are more surprises in the store, as Kirk discovers that the alien may not be everything he seems. This first season episode was directed by Joseph Sargent, who would later helm The Taking of Pelham One Two Three and numerous other feature films.

Audience Reviews for Star Trek: Season 1

  • May 01, 2021
    Season 1 of Star Trek is basically just your average 60's show, and it shows. You can sort of tell that Gene Roddenberry and the rest of the crew were new to the idea and hadn't learned to fully develop it quite yet, as about half or more of the episodes feel messy, as well as slow throughout almost the entire episode and very rushed in the last few minutes to keep the runtime 50 minutes or under. The designs of the characters also don't hold up well too much, which was distracting and even sickening for me. However, I do recommend this to Trekkies, as this is still a competent addition to one of the biggest sagas in entertainment history.

    The 1st season of the Original Series is a fantastic introduction to this franchise. My favorites for this season are The City on the Edge of Forever, Balance of Terror, Space Seed, The Corbomite Maneuver, The Devil in the Dark, The Enemy Within, The Mengerie, Tomorrow is Yesterday and Arena

    Cool 60s show man I love it
  • Oct 27, 2020
    Wow that was so great
  • Oct 15, 2020
    It cracks me up that people under the age of 35 can't understand that this show was groundbreaking for its time while it navigated the whim of tv executives and sponsors pulling out due to a black woman on the bridge... The sets are cheesy and the optical effects are sloppy but, so what? We thought the show looked cheesy back in the 80's when I was a teenager. But it was the stories, characters and ethical dilemmas that made it special. Get over your babyish desires for instant gratification and anything that bruises your delicate sensibilities. Was there sexism in 60's Trek? absolutely. It was baked in the fabric of the time. At least they put a lot of care in the 1st 2 seasons (and a few episodes of the 3rd) and you wouldn't have world-building franchises and cos-play or even Star Wars if it wasn't for this show. Period.
  • Jul 07, 2020
    My favorite series of the 1960's. Classic series.
  • Apr 10, 2020
    Although it may appear very campy, It utilizes that campiness to create an intriguing, and sometimes funny, watching experience. Another benefit is the amazing casting and crew, they compliment's each other's personalities wonderfully, becoming even better in Season 2.
  • Feb 18, 2020
    Decades ahead of it's time, progressive on every front, and some of the smartest Sci-Fi writing of all time. Star Trek challenged the status quo of it's day, but made all the better for wonderfully hammy performances from the main cast. A true classic and a cultural delight.
  • Feb 12, 2020
    Absolutely fantastic!
  • Feb 10, 2020
    Excellent show for the time, but too slow for today. The greatness of it is the origin of the saga
