R U Invited? 2006 ( 5.8)

Five friends receive invitations to an underground sex party. However, to qualify for attendance each invitee must submit revealing photos as a "screening" process." As the party draws near, issues of monogamy, weight & appearance, discrimination, drug use, and promiscuity arise. Friendships are tested and pushed to their boundaries, personalities collide, sexual histories are revealed, and relationship survival is in question.
