Breaking Bad: Season 4 (2011)

Walt and Jesse are held captive for Gus, after Gale's death. Meanwhile, Skyler tries to find out what happened to Walt.

Shaken by Gus's calm violence, Jesse cokes up; bleary-eyed and jittery, he throws a party. Walter, believing it's kill or be killed, buys a snub-nosed .38 on the black market, intent on shooting Gus and Mike. Skyler looks to launder money at a car wash, and, to Hank's increasing irritation, Marie insists on cheering his every step. Men deliver boxes of minerals and pick up boxes of crystal.

Skyler finds a way to pressure the car-wash owner into selling, while Marie goes on a series of visits to realtors' open houses. Her antics get her in trouble, and Hank has to pull a few strings. One of his cop friends helps Marie out and, in turn, asks Hank to look at a notebook found at the scene of a murder. Meanwhile, Jesse's round-the-clock open houseparty brings no mirth.

Walt and Skyler have decided to use gambling to explain how Walt has made all of his money. It's not to be a happy story and Skyler insists that Walt admit to a gambling addiction and express deep shame for what he has done. At dinner with Marie and Hank Schrader, they tell their rehearsed story. Hank has a story for Walt however, one of a dead wannabee singer who had lab notes describing a super-processing meth lab. Hank is convinced the dead man is Heisenberg, the drug manufacturer he has been looking for for over a year.

In his attempt to save Jesse, Walt visits Gus' fast food restaurant but isn't quite prepared for what he learns. Nor is Jesse for that matter. In fact, he proves to be quite useful though not everything is as it seems. Hank is convinced that Gale Boetticher was Heisenberg and tells the local police detective that he really has no further interest in the case. He mentions that Jesse Pinkman could have been involved but is not likely the shooter.

It's the morning after the night before and Walt has a major hangover. Skyler is now convinced that Walt is in danger but he makes sure she understands exactly how important he is to the criminal organization. He's a little too blunt as Skyler's reaction is to take the baby and disappear for a few days. One of Gus' trucks has been hijacked so Mike and Jesse are tasked to get the blue meth back. Once again, Jesse proves to be unexpectedly useful.

The car wash is now in operation but Skyler isn't prepared for the amount of money Walt is bringing in. She also arranges for Walt to return the car he bought Walt Jr. but in the end decides he has other plans for it. Walt still believes his life is in danger as long as Gus is alive and speaks to Saul about how he wants to hire a hit man. He finds someone closer to home. Hank and Walter Jr. visit Gus Fring's chicken restaurant and Hank has something very specific in mind. He's slowly putting the facts together in his quest for Heisenberg.

Hank's discovery of Gus Fring's fingerprint in Gale Boetticher's apartment is enough for DEA and Albuquerque PD to bring Gus in for an interview. He seems to have an answer for everything, including why his fingerprint was found at the crime scene. Everyone but Hank seems to be satisfied and they decide not to pursue the matter. Hank isn't so sure. Gus realizes how close he's come to being caught and in flashbacks, his entry into a world of crime and his work with the Mexican drug cartel is revealed.

Hank is like a dog with a bone and keeps digging into Gus Fring's business dealings despite Walt's attempts to get him to stop. When Hank learns that Gus has a warehouse operation, Mike and a crew have to get rid of any trace of drugs on the premises. The Cartel however is lying in wait. When Jesse expresses concern over his future well-being Gus asks him over for dinner and asks him one question: can he cook Walt's recipe without Walt's assistance. Skyler meanwhile gets a visit from her old boss who reveals that he's about to undergo an IRS audit.
