A truly Grand Guignol play with rapacious servants venomous Dobermans meat hooks and mutilations. In a gothic mansion in England lives a grande dame with three servants and on this occasion a small grandson whose parents are traveling abroad. Two men masquerading as telephone repairmen abduct the grandson for ransom and the grandmother in order to keep hidden certain family skeletons readily pays. But then the bloody machinations begin and before the grisly ending there are multiple disclosures including the discovery of a Nazi death camp commandant.
