If you've ever had a bad day, a really bad day, you'll know what drives Joan to swear she'd do anything to erase such a miserable experience. Unfortunately she says it with enough sincerity to bring the soul-bargaining devil himself, a quiet-spoken and distinguished gentleman, who agrees to let her do just that. In this comedy, Joan finds out that even when she thinks she's had the last laugh, the devil always has a few new tricks.
