They were not the marrying kind, so they agreed that neither one could wed until his pal had tried to win his girl away! The funniest love-test ever made, with thrills and laughs galore when they both fall for the same girl!

Gunner and Bucker are friends who work as riveters. Whenever Bucker gets the urge to marry, which is often, Gunner will hit on his girl to see if she is true or not. So far, Gunner hasn't failed. But one night, while Gunner is in jail, Bucker meets Mary, a tough dame with a line. He falls for her, and she falls for his money. But Mary is already a gal pal of Gunner, and no two know about the third one. The trouble starts when the triangle is revealed too late.
