"Heat" is a parody of "Sunset Boulevard." Joey Davis, an unemployed ex-child actor, uses sex to get his landlady, Lydia, to reduce his rent, and then tries to exert his influence on Sally Todd, who is now washed-up and wasn't even more than slightly important at the height of her career. Sally tries to help Joey, until he realizes that she just isn't well-connected enough to be of any service to him. The affair is complicated by Sally's psychotic, maybe-lesbian-or-maybe-not daughter Jessica, who tries to muscle in on her mother's relationship with Joey.
