Long-term couple Simon and Jason, along with daddy-ish Cooper and his boy du jour, escape to a mountain cabin for a three-day weekend away from their hectic city lives. Looking to spice up this long-standing tradition, they add a special twist to this years retreat - each of them must invite one attractive single friend to their mountain getaway. Arriving are a frisky former college roommate, a constantly naked yoga instructor, Jason's uptight co-worker and a high-priced rent boy who do indeed stir up the weekend. But this combination of new and old friends creates more tension than anyone ever anticipated. After 72 hours and multiple sexual couplings, new relationships form while others are cast onto shaky ground.
