Max's father, Ed (Colm Feore), is a tax attorney with a more laid-back approach to his son's future, just wanting him to be happy.
Before long, Max and Molly are becoming an item, the two even managing to make love in his bedroom with his mother and younger sister Chloe in the house.
Max invites Molly to Chloe's birthday party, and though she initially refuses to attend because it's the same night as a Smashing Pumpkins concert, she later relents.
A short time later, Molly celebrates their new-found relationship by having them shoot up together in her apartment, and Max soon becomes hooked, neglecting his studies and job.
His addiction now totally out of control, Max tries to rob a local comic book store for drug money, but is caught by the police.
However, while this discussion takes place, Max manages to slip out of the hospital and begins frantically searching for Molly, finally finding her in a sleazy motel room where she has died of a heroin overdose.
Out of his mind with grief, Max shows up at Kate's apartment and begs her for money; when she refuses, he accuses her of "wanting" him and offers to prostitute himself.
Informing his mother of Molly's death, the two tearfully embrace, and as he prepares to leave for his month-long stay in rehab, he and Sophie finally reach an understanding.
