Mary-Kate and Ashley play wildly different estranged sisters who live on other sides of the country.

Unknowingly and much to their surprise, they are selected for the same team on a popular TV reality show The Challenge.

In order to win the grand prize of college scholarships, ambitious, uptight Lizzie (Ashley) and laid-back care free Shane (Mary-Kate) have to learn how to live with each other or else their reward is on the line!
