Hayden and Nick used to be a hot item, but their brief affair ended with a highly publicized breakup. Now the two are "just friends," excluding the occasional flirtation.
When Hayden wins the girls' division of a local snowboarding competition, Nick is unimpressed, claiming that Hayden wouldn't have a chance against a guy. Hayden calls Nick's bluff and challenges him to a head-to-head boarding contest. Their mutual friends quickly take sides, the girls on Hayden's and the boys on Nick's, making for an all-out battle of the sexes. This friendly competition is bound to get heated -- and they might end up igniting some old flames.
