Abroad with Two Yanks: Biff and Jeff, two American G.I.'s on furlough in Australia during The Second World War, are enjoying their time the way most soldiers on leave do.

As their R&R time begins to run out, the schemes they each come up with to win her affection and foil the other's plans to do the same become more and more outrageous.
