Young Libby Parsons (Ashley Judd) is happy as a clam, and why not? She's got a loving, successful husband (Bruce Greenwood), an adorable son, and an island home to die for. One morning, after a romantic sailing expedition with her husband, Libby finds herself covered in blood. Her husband's missing, the boat resembles a murder scene, and there's a knife on the deck. One might stop right there and call for help; Libby, however, takes matters--or, more specifically, the knife--into her own hands, and the moment she does, there's the Coast Guard. Faster than you can say frame-up, Libby's been charged with murder and jailed, with her young son stripped from her custody. It's all cut-and-dried, except for one thing: Libby's husband isn't dead, and she's about to track him down. And thanks to the Fifth Amendment's double jeopardy rule, she can't be charged twice for his murder.
