Abroad with Two Yanks

On leave in Australia, U. S. Marines Biff Koraski (William Bendix) and Jeff Reardon (Dennis O'Keefe) look forward to finding romance. Despite their friendship, Jeff feels no guilt over stealing Biff's girlfriends, so the men begin a competition for the attentions of pretty Australian girl Joyce Stuart (Helen Walker). After Biff rescues Joyce's friend, Jeff assumes his friend's identity to win the grateful Joyce's affections -- and Biff retaliates by having Jeff declared a schizophrenic.
