An ambitious high school senior who dreams of escaping his dreary small town and his depressive single father receives a visit from a disheveled senior citizen claiming to be the boy's older self in an intimate fantasy drama starring Robert Loggia, Craig T. Nelson, and John Amos. Seventeen year-old inventor Z.T. (Ean Mering) is athletic and creative, and seems to be headed for a bright future. Lately, Z.T. has been dreaming of getting out from under the protective arm of his gloomy father Cole (Nelson) and venturing out into the real world. Suddenly, sixty-eight year-old alcoholic named Zack (Loggia) shows up in town claiming to be the older incarnation of Z.T. Despite the fact that Zack can't quite remember the specifics about his mission, he claims to have arrived in order to stop Z.T. from making a single mistake that will send the boy's life into an irreversible downward spiral. Later, as Zack and Z.T. begin working together to avert disaster, the young boy falls for a beautiful local girl named Delena (Emilie Jacobs) and does his best to deal with the demands of his overbearing coach (John Amos). When Z.T.'s dad makes a devastating confession, Zack's time-traveling mission quickly takes on a newfound sense of urgency.
