Teenager Marisa whittles wood outside her high school. After a teacher takes Marisa’s knife, she follows him and beats him. The Principal later reprimands her and, as a punishment, orders her to volunteer as a candy-stripe nurse’s aid. At Oakwood Hospital, a candy-striper, Sandy, and Wally, a doctor, have sex in the linen closet. That night, Carlos, a young man, asks to use the bathroom at a gas station but is caught in the middle of a robbery and later shot by the attendant who assumes he is an accomplice. Marisa, now a candy-striper, tends to Carlos in the hospital, and he asks her to scratch his back. Noticing that he is handcuffed to the bed, Marisa realizes Carlos is a criminal; however, he claims he was wrongly accused. Elsewhere in the hospital, Dianne, another teenaged candy-striper, asks Dr. Wilson for permission to follow him on his rounds. They later discover Sandy naked in the room of a patient with whom she was having sex. Shortly after, Dianne sees Cliff, a basketball player, fighting off doctors in a rage. After Cliff is tied down, Dr. Wilson orders a blood test to screen him for drugs. Dr. Krause, Cliff’s sports doctor, arrives and tells Wilson that his patient took a hard blow to the head. Krause discourages Wilson from ordering any blood tests, then demands to be alone with Cliff. The next day, Dianne talks to Cliff about basketball, likening it to her passion, which is dance. She later films home movies of his college team’s basketball practice. After practice, he takes her to the gym and seduces her. One day at the hospital, Carlos convinces Marisa that he is innocent and tells her that the only witness to the crime had a multi-colored motorcycle. Hoping to exonerate Carlos, Marisa searches for the witness, using a sketch of the motorcycle to track him down. She talks to the gas station attendant who believes Carlos must be a criminal based on the way he looks. At the hospital, Sandy agrees to fill in for the receptionist at the sex clinic, where rock star Owen Boles arrives with Freddie, his personal manager, and two girlfriends. Sandy eavesdrops and hears Freddie tell Dr. Kramer that Owen suffers from impotence. Kramer orders Sandy to call Jane Ellington, a therapist who performs home visits, and direct her to see Owen at his home the following day. Instead, Sandy informs Jane that she will not be needed, planning to go in her place. Outside the hospital, Sandy runs into Wally and breaks up with him. Meanwhile, Dianne goes on a date with Cliff and later sleeps over at his apartment. Cliff admits to taking amphetamines, and Dianne disapproves. The following day, Sandy shows up at Owen’s house and meets the rock star by his pool. When she asks if he finds her attractive, Owen demurs. She then kisses him, but he doesn’t respond. Frustrated by his lack of excitement, Sandy storms away. Elsewhere, Marisa continues to look for the witness to Carlos’ alleged crime, whose name, she has learned, is Eric Garcia. A hoodlum notices Marisa at an auto shop where she inquires about Garcia and follows her to the next stop on her search, a convenience store. There, a woman informs Marisa that Garcia works at a junkyard. In the parking lot, the hoodlum stops her and tells her she will not find Garcia at the junkyard but at a restaurant, Las Palomas. He tells her to go there and ask for Eddie in the kitchen. At Las Palomas, Eddie offers Marisa money for sex. She tries to get away from him, but he holds her at gunpoint in the pantry. While he attempts to rape her, Marisa grabs Eddie’s gun and turns it on him. She escapes and goes to the junkyard. There, she finds the multicolored motorcycle and Garcia. When Marisa asks the witness to testify in Carlos’ defense, Garcia nervously asserts that he saw Carlos shoot the gas station attendant. Upset by the news, Marisa leaves. The hoodlum, who has been holding Garcia at gunpoint, appears and threatens the witness to stay quiet. At Carlos’ hospital room, Marisa angrily repeats what she learned from Garcia, but Carlos continues to defend his innocence. Later that day, Marisa remembers that she tore her dress on the hoodlum’s car at the junkyard, though she hadn’t realized the hoodlum was there at the time. Rushing out of the hospital, she tells a nurse to call the police and send them to the junkyard. Returning, Marisa finds Eddie tying up Garcia and a junkyard client. Eddie shoots Marisa, but she retaliates, hitting him with a metal rod. Garcia steals Eddie’s gun and pursues the hoodlum, who runs into a policeman as he leaves the junkyard. Later, Sandy returns to Owen’s house, claiming that she left her purse. Owen tries to seduce Sandy, but she pushes him off. He throws her down on the couch and she fights him. Excited by the action, Owen’s girlfriends strip naked and join in. Freddie arrives and pulls Owen off Sandy. Claiming to have cured his impotence, Sandy leaves Owen to have sex with his girlfriends, and joins Dianne at Cliff’s basketball game. In the locker room during the game, Cliff asks Dr. Krause for drugs. After his team wins, Cliff takes Dianne and Sandy for a ride. Inebriated, he drives recklessly, knocks over a post office box, and finally crashes the car. When an ambulance delivers Cliff to the hospital, Dianne frantically informs Dr. Wilson that he has the wrong information regarding Cliff’s blood type. Before Wilson administers a blood bag, Dianne explains that Krause provided a false blood sample for Cliff the other day to cover up the fact that he’s been illegally supplying drugs to him and other basketball players. After a successful operation, Wilson declares that Cliff will be alright. That night, Marisa receives treatment at the hospital for her bullet wound, and Sandy reunites with Wally in the linen closet.
