A writer finds out that his wife is leading a double life, which includes a second husband who lives on the other side of town. He presents this story to his editor, who is so intrigued by it that she takes her male secretary along and sets out to find out whether the writer's wife is actually doing what he says she is.

Two young girls in New York's Greenwich Village own a plaster-casting shop. One day a well-known Hollywood actor walks into their shop and asks if they can make a plaster replica of his penis. When he later brings a friend of his, also a well-known actor, in to get his 'member' replicated, the girls hatch an ingenious plan to make a lot of money by making replicas of stars' penises, then blackmailing them. However, things don't turn out exactly the way they planned.
