Theatrical Release Information:
The Mayor of Hell

Gangster Cagney allows his powerful political connections to appoint him "deputy inspector" of a state reform school. There he finds the youths abused and battered by a brutal, heartless warden and his thuggish guards. It is a nurse who informs Cagney and pleads with him to clean things up. Something touches Cagney's normally hard heart and he commits himself to enacting more humane reforms. Soon, he gets the warden booted out and begins working closely with the inmates, who come to trust and respect him until Cagney's dark side emerges and he reveals himself for what he is--a ruthless mobster. This destroys the boys' trust and when the old warden is reinstated makes matters even worse until Cagney makes a difficult choice. ~ Sandra Brennan, All Movie Guide
