Including Gregor (Christopher Lee) in a black mask, a lion tamer who apparently was horribly scarred. Gregor is training Natasha (Suzy Kendall) but has a secret which the ringmaster Carl (Heinz Drache) is determined to find out. Meanwhile Gina (Margaret Lee) is in a tempestuous relationship with knife-thrower Mario (Maurice Kaufmann) and is found dead with a knife in her back...
After a high energy opening the film does bog down a bit when it reaches the circus but the various sub-plots and red herrings make for a very enjoyable film. One of Christopher Lee's more unusual roles. The identity of Mr Big who organised the robbery and performed various killings is a genuine surprise.
