Vincent has designed a brand new building and proposes that he and his friends share one of the wonderful penthouse lofts. This would allow them to hook up with other women without worrying about hotel charges showing up on their credit cards. When they discover the body of a beautiful woman cuffed on the bed in the loft, they argue over whom is responsible and secrets are disclosed affecting their friendship.
