A woman arrives at a lonely mansion and finds herself mixed up with a lunatic who has built his own torture chamber, which is already crowded with victims - and he plans to make her his next one.
Two murder victims have turned up in London; one was found floating in the Thames, the other suffers what appears to be a heart attack at a soda stand. Both have one thing in common: they each had a mysterious key attached to a gold chain. Scotland Yard Inspector Richard Martin (Drache) investigates (with his veddy-British comic relief partner Holms), and discovers there are seven keys in all. But where is this door with seven locks? And what does a young heir coming to town for his 21st birthday have to do with it? The mystery involves a mad scientist conducting genetic experiments in the basement of a spooky old castle. This German-made black-and-white "krimi" based upon an Edgar Wallace story is fast-paced and fun.
