Small-town auto mechanic Benny has devoted his life to caring for his schizophrenic sister, Joon, who isn't capable of living on her own. Her behavior drives away all of her caretakers, and Benny is informed by Dr. Garvey (Joon's psychiatrist) that it is time to consider placing her in a group care facility where she will be with her peers. The following day, Joon is picked up in the street by the police after Benny leaves her at home unattended to go to work. All of the days' events diminish Benny's sense that he can take care of Joon, and his friends later add to his dilemma by telling him about all the things he could be doing with his life if it weren't for Joon.
