Neurotic businessman Greg Brentwood (Michael Kitchen, Foyle's War) throws an extravagant anniversary party for his wife, Linda (Phyllis Logan, Downton Abbey), at their English country home. One of the caterers, Marcey (Sophie Okonedo, Hotel Rwanda) quietly admires the couple's love for each other-until she sees an intimate moment between Linda and Greg's business partner, Martin. When Marcey later returns to the house to retrieve her handbag, she walks in on a frightening scene: Greg moving Martin's lifeless body. After the initial shock, Greg assures her it was an accident, and Marcey offers to help him dispose of the corpse. As the police investigate the death, Greg becomes increasingly anxious, while Marcey urges him to remain calm. But as she starts to uncover the Brentwoods' darkest secrets, she begins to wonder what she has gotten herself into. This intriguing and darkly humorous thriller from multi-award-winning writer Paul Abbott (Shameless, State of Play) also stars Adam Kotz (The Last King of Scotland) and Hilary Maclean (Torchwood).
