It seemed harmless, but the affair that Alan (Joseph Fiennes) began with Ella (Gretchen Mol) would have deadly consequences. No level of passion on their part could erase the fact that Ella's husband Mark (Ray Liotta) has sworn vengeance. Mark's detestation of her betrayal brings out his vicious side, and the two men begin a decades-long vendetta that continues long after the deeds are forgotten.
