Prestigious specialist Frank Henson and his wife Hillary become held hostage in their country home when Henson opens the door to escaped convict Garard and his sidekick Filton. Garard, a notorious killer, agrees not to harm the couple as long as they co-operate, but then an unwanted guest in the form of journalist Tracy Loxton arrives. Loxton claims she had made an appointment to see the Henson's collection of poster art weeks beforehand and, despite the best efforts of the doctor, insists on seeing the house. An elaborate deception then ensues, with the unbalanced Garard reluctantly playing the part of the Henson's butler while they wait for the girl to leave. Yet Garard is perhaps not the only killer present in the house.
