J. Harold Manners (The Uptown Boy), a debonair young millionaire in search of a downtown restaurant, passes an evangelist's coffee stand and accidentally starts a fire; Harold contributes a thousand dollars for damages, which the evangelist uses to open a mission named for the donor. Coming to protest this honor, Harold meets Hope, the evangelist's daughter, and offers to help her bring in the poolroom toughs and gangsters. He draws them into a chase, and with the aid of the police, he retrieves the property they have stolen. Harold's club friends abduct him to prevent his marriage to Hope, but his slum cronies come to the club and rescue him. The race back to the mission turns into a melee of trials and tribulations for Harold as his inebriated friends wreak havoc; and at the mission Hope and Harold are married amidst the cheers of the converts.
