When an injury ends his amateur boxing career, Stuart Long (Mark Wahlberg) moves to L.A. dreaming of stardom. While scraping by as a supermarket clerk, he meets Carmen (Teresa Ruiz), a Catholic Sunday school teacher who seems immune to his bad-boy charm. Determined to win her over, the longtime agnostic starts going to church to impress her. But surviving a terrible motorcycle accident leaves him wondering if he can use his second chance to help others find their way, leading to the surprising realization that he is meant to be a Catholic priest.
