It seemed harmless and fun, but the affair that Alan (Joseph Fiennes) began with Ella (Gretchen Mol) at the resort where he was working 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 detest of her betrayal brings out his most vicious side, and the two men begin a decades-long vendetta which continues long after the deeds are forgotten.
