Things go dangerously awry when the thrill seeking Emery engages in an adulterous fling with the wildly free-spirited and exotic Allanah. Timing couldn't be any worse when the politics of high society, shady business deals, bad press, and a violent murder collide, they threaten to destroy more than just his shaky marriage. As police probe into his situation, they uncover a labyrinth of deception, agendas and motives, where the stakes are enormous and nothing is what it seems.
