Everyone is on a collision course as they arrive at the Winter Festival on Llantano Mountain. Cole and Starr's carefree evening together turns into a nightmare when they spot Marty and then Blair and Todd. Todd is amused by Blair's predicament when Miles admits Marty is at the festival with him. Still hurting over her break up, Evangeline argues with Layla when she sees her sister with Cristian. Although not angry, Marty sets Miles straight about telling the truth and not making assumptions about dates. Rex draws his line in the sand with Tate where Adriana is concerned. Things go from bad to worse when the road down the mountain is closed due to weather. As night falls, Blair, Evangeline, Layla and Marty are forced to share one room and are soon at each others' throats. Down the hall, Todd, Miles, Tate and Cristian make miserable roommates. Starr, Cole and Langston end up sharing space with a scheming Britney. Rex and Adriana, however, end up by themselves for the moment.
