Joe Adams (Cary Grant) is as clever as they come. Certain that he'll be called up during World War II, Joe nabs the draft papers of a man who's been freed from service and leverages his position into a potentially lucrative scam. The captain of a commercial ship, Joe cons war volunteer Dorothy Bryant (Laraine Day) into believing that he's planning a fund drive for the troops. In fact, he's got something more devious in mind. But as Joe rethinks things, he finds his ruse is already in motion.
