Chemistry 2 (2007)

Director Tristan Taormino takes eight new porn stars to a secluded house for 36 hours. Each is strong-willed, each is unique, and the only thing they have in common is that they work in adult films. As they get to know each other, what happens is completely up to them; they make the decisions. They know in advance who they'll have sex with, but when, where, and how is totally their call. The action is fast and spontaneous, the hook-ups explosive.
