Ava (Mandy Moore) and Charlie (Kellan Lutz) are newlyweds that have been inspired by the 30-year marriage of Ava's parents, Bradley (James Brolin) and Betty (Jane Seymour (actress)) when Ava decides to throw them a surprise anniversary party. But when Betty finds out about an affair Bradley had 25 years ago, she refuses to live with him, which then forces Ava into moving her father into her house, without consulting Charlie. She promises her new husband that it will only be for a short while. Being a marriage counselor, Ava tries and starts to obsess over fixing her parents' marriage so much that it starts to affect her relationship with Charlie. Their marriage starts to deteriorate when they stop having sex and becomes worse when their friend Gerber and new Poles wife, Kasia, whom he had met the night before, show up and he tells Ava about Charlie’s first marriage 10 years ago, that she never knew about. When she hears about it, she becomes upset and Charlie tries to explain that it was a long time ago and he was under the influence of alcohol when it happened.
