Hannah Haynes, a pretty girl who competes in a beauty contest, dreams of moving away from her New York slum neighborhood. Her older brother Chuck, who has a chance to land a new job on Long Island, is hit by a car and needs to recover first.
Hannah frustrates her boyfriend by agreeing to a date with a hoodlum named Irv Kellener, which causes a fight between the men and makes the evil schemer Vera Schroeder jealous.
Chuck and his girlfriend Georgia, who does seductive dances to entice men to throw coins to her, become so desperate that they steal from a beggar who is pretending to be blind.
Anticipating their plot, Irv arrives there first but is caught by the beggar and shoots him. Vera hides the gun and provides an alibi.
Chuck and Georgia later execute their plan and steal more than $600, unaware that their victim is dead. Vera blackmails them, demanding $2,000 to prevent her from snitching to the police.
The principals confront each another in a warehouse, where Irv kisses Hannah and infuriates Vera. The police arrive, Irv runs and he is accidentally electrocuted.
Chuck and Georgia are set free after returning the stolen money
