It’s early July in Philadelphia. Childhood trauma has its hold on Harris Malden: he has no facial hair, so to compensate, he draws a mustache or beard on his face every morning, and he won’t leave his neighborhood. His younger brother, Melvin, his best friend Paul, who lives next door, Paul’s grandmother, and the entire neighborhood play along. But at the party for his 25th birthday, Paul’s new girlfriend Susan points out to Harris that his mustache is a fake. This causes a crisis in Harris and threatens the friendship with Paul. Meanwhile, Melvin is trying to break into TV commercials. Hair, honesty, growing up, and moving on challenge each character and each relationship.
