To gain the inheritance of their rich dying father, two estranged half-siblings need to prove they can work together to survive a week in the desert. If they can't, they risk losing it to their father's new trophy wife and his lawyer.

The only thing millionaire Ted Hurst has never been successful at, is getting his uptight son Eric and slacker daughter Ellie to get along with each other. With Ted's recent terminal diagnosis, he's out to prove that they can be a family again while raising the stakes and putting his estate inheritance on the line. With the assistance of his longtime greasy attorney Miles, Ted sends Eric and Ellie out to a deserted location for one week with only the clothes on their backs in hopes that they will learn to survive together--literally. If they can get through it, they will earn their father's fortune. If they can't, Ted's tough love experiment will prove wrong and Miles believes he will be next in line for Ted's empire with the help of Ted's new trophy wife, Anya. Can Eric and Ellie work together for the first time in their lives when it really counts? After all, it's Just For A Week.
