Plot hole: At the end, if Margaret had followed Alek's plan and waited in the driveway after he killed Nagel, the police would have found Alek dead in the car crash with the video, which they would certainly have played, leading to not only Beau becoming a suspect , but also revealing his homosexuality - two issues they were blackmailing her for. Alek sacrificing his life would be in vain, except, perhaps for his own redemption.
