Some secrets keep a couple together. If you ask Jill Tingley, she'll tell you she and her husband Jack are college sweethearts living the dream in Southern California. Wealthy, popular and genetically blessed, theirs is an enviable life, though they've grown distant in recent years. Newly empty nesting with their daughter Maggie away at college, Jill suggests a road trip to reconnect. Jack would rather do anything else than drive to Utah with his wife. He's only stayed in this marriage because of a shared secret, a tragedy in the past he wanted to keep buried. And for his daughter's sake. But Jack is finished with the charade of his marriage. He's filing for divorce as soon as they return, no matter what. But he doesn't realize what else Jill is hiding. So begins a cat-and-mouse road trip as a cunning wife - think Ripley in yoga pants - and a reluctant husband match wits and drive each other to the edge. But everything will be fine. Jill still loves Jack and believes he's the only one for her. She'll do anything to keep him. Anything. She always has.
