Two years ago, Ellie Grant would have fallen apart at any reminder of her ex-husband, Tucker. But now she doesn't bat an eye when "their song" comes on the radio. She's unfazed by the thought of Tucker's perky new girlfriend. Ellie Grant is over him. And things are better for Tucker as well. The single life agrees with him. And certainly they've both done a good job of being civil to each other, for the kids' sake.

But the kids aren't buying it. Zach and Kody are convinced that, deep down, their parents are still meant to be together. Up to their elbows in scheming and dreaming, the brothers hatch a plan: They'll run away from home into the Oregon wilderness and stay there until their parents agree to get back together. Surely Ellie and Tucker will come to the rescue--and to their senses.
