Claire, a mild-mannered parking attendant, lives in a small flat with her mother who is recovering from a recent stroke. In the opening sequence she patrols the Los Angeles streets and stumbles into an old flame, who introduces Claire to his wife and ill-behaved daughter. Reeling from the chance encounter, she steps out onto the street and is hit by a passing vehicle.
Returning to work three weeks later, Claire attracts the attention of another parking attendant, an extremely blunt and aggressive man named Jay whose home life consists mainly of entertaining himself using the services of a webcam porn site and phone service. Claire witnesses him fighting with her best friend, a neighbor working for a delivery service who parks on the curb to unload her consignment, but does not bring it up with either party.
She develops a crush on Jay, but in each conversation Jay takes issue with some entirely innocuous comment Claire has made and storms off in disgust. Nonetheless, he keeps coming back for more. One night as Claire prepares to join him at the annual office Christmas party, she finds her mother slumped overâdeadâin a bowl of mashed potato.
In shock, she simply picks up her coat and leaves for the party. She sits alone, watching Jay dance with another woman, until finally Jay asks in brutal terms what is the matter. She takes him home to show him the problem.
Claire decides that rather than call an ambulance she prefers to have the situation dealt with by family. She calls her mother's vain and self-obsessed sister, who lives in a different part of the city. Her aunt says it is too far to come at that hour of the night, but if she wants to, Claire can come pick up a necklace belonging to her mother.
After calling an undertaker who takes the body of Claire's mother away, Jay insists on staying the night to "take care" of Claire, promising to sleep on the couch. But he goes to Claire's narrow bed and starts to remove her clothes. After a few seconds of brutal thrusting, during which he talks to her as if she were the phone sex service he uses so frequently, he rolls over and falls asleep.
From that point on, Jay and Claire maintain a tenuous sort of relationship, hung mainly on Claire's optimism and Jay's desire for sex and attention. At work, Jay is suspended for his aggressive behavior with parking offenders, which has earned him an impressive complaints record. He watches a crafts documentary on carpentry and decides to make a love seat.
Jay offers to drive Claire to her aunt's house in Pasadena to pick up her mother's necklace, lying to her over his disciplining at work. He drives her to the other side of the city, with her seated on the makeshift love seat in his parking attendant's vehicle. Her aunt insists that they all go out drinking; Jay and Claire end up in a hotel room. Jay gives Claire a tiny, pink PVC bikini and tells her she should lose weight, which Claire takes in stride, as she has previously with his other insinuations and outright insults.
During her next shift, Claire is informed that she is being promoted for her exemplary behavior. To celebrate she goes to Jay's apartment but swiftly realizes that he was visited by a prostitute immediately before her arrival. She leaves in disgust.
Jay goes to her apartment to apologize. Dressed in a more fashionable and confident style, she is outspokenly skeptical about his behavior, but submits when he pulls her to the floor for another round of uncomfortable sex. When it is over, Jay expresses that he has burgeoning feelings of commitment to Claire, but she asks him to leave.
In the final scene, Claire once again walks her beat alone. Another vehicle nearly catches her at the site of her prior accident, but this time she escapes unscathed, and smiles in relief. The closing credit song was custom written, produced and performed by Max Sharam though she never received a credit.
