This film was originally meant to be broadcast on British TV. It consists of four episodes showing different points of view from each of the four main characters depicting the members of a wealthy, privileged family. One family member has been killed, and as each episode unfolds, the viewer gets to see secrets revealed, behaviors revealing psychological damages, seduction, revenge, all leading to different murder plans by each member. The actors are excellent, the story is compelling. The characters are flawed, human, and one begins to care for some of them. I thoroughly enjoyed the film. It kept me guessing till the end.
