The film stars David Proval, James Andronica, Morgana King, Joe Spinell, Tovah Feldshuh and Maria Smith.
Nunzio is fixated on elements of superhero stories; he wears sweatshirts that he has emblazoned with a shield and a capital "N" in the style of Superman, along with a cape, and often jumps across his neighborhood's rooftops.
He becomes infatuated with Michelle (Tovah Feldshuh), an attractive employee at the local bakery, but when he expresses his affection, he is heartbroken to learn she is married with a child.
He begins to refuse tips for delivering groceries, feeling that since Superman never asks for money for doing good things for people, neither should he, which worries his mother and brother.
Most of the tenants escape, but Nunzio notices a remaining resident who is still stuck in her apartment and climbs back up to retrieve her; she is revealed to have leg braces.
