Battle of the Ex's *Christmas Edition

This is not your typical Christmas story. Here's why: Mia and Ethan used to be high school sweet hearts. But when Ethan's dad, a developer, threatened Mia's family about giving up their land so he could build houses, it tore them apart and made them enemies. They finished high school competing in the made up contest, 'Battle of the Ex's', where Ex's from all over the high school compete in challenges to prove which one is the best. Now they're going to the same college, and stuck in the same dorm. Mia has managed to avoid Ethan, even going as far as to do her laundry at the local laundromat. Until Christmas Eve that is. A freak storm and loss of power leaves Mia trapped in the common room with Ethan and two others. Having still not forgiven Ethan, Mia suggests they continue on with the Battle of the Ex's Christmas Edition. A head to head competition to see who, once and for all, is the better Ex.
