Harold Lloyd plays a wealthy young spendthrift who is upset that his name is being used to bring parishioners into a storefront mission in the poorer part of town. He heads to the mission to have it out with the minister, only to fall in love with minister's daughter Jobyna Ralston. Realizing that the use of his name as an endorsement was an honest error on Ralston's part, Harold decides to help the girl's father attract worshippers and hymn-shouters. He goads a bunch of thugs and pluguglies into the mission, then makes certain that they stay--and secures their undying loyalty--by saving them from being arrested. Harold and Jobyna decide to get married, whereupon Harold's wealthy chums, dismayed that he is marrying beneath his station, kidnap the poor fellow to prevent him from making a "mistake". Harold is rescued by his tough-guy slum pals, but not before they've gotten themselves drunk and commandeered a double-decker bus. The climactic chase is as hilarious and exciting a piece of celluloid as has ever been produced, but it is merely the capper to an uninterrupted stream of brilliant sight gags. Long underrated, For Heaven's Sake is one of the cleverest and most consistently entertaining of all of Harold Lloyd's silent vehicles.
