Lord Curtain is murdered in his castle, allegedly by the RINGER (Rene DELTGEN) according to a business card left at the crime scene! The super criminal, who had long since gone into hiding in Australia after his adventures in the film THE MAGNIFICENT SORCERER, cannot let this happen. Together with his wife Cora Ann (Margot TROOGER) and butler Finch (Eddi ARENT), he sets out on his own to find the perpetrators. Meanwhile, the rest of Lord Curtain's family is also in danger. Margie Fielding (Barbara RÜTTING) and Lady Aston (Brigitte HORNEY) turn to Scotland Yard for help. Since Inspector Higgins is still on his well-deserved honeymoon, Sir John (Siegfried SCHÜRENBERG) promptly reactivates the Australian Inspector Wesby (Heinz DRACHE).
The RINGER once again delights with his many masks in the second part. But it also gets very scary. Basically, an entire family is to be wiped out out of selfish revenge. Other roles are played by Klaus KINSKI, Robert HOFFMANN, who still speaks in the strong Austrian dialect, and the later CINECITTA diva Gisela HAHN. Very impressive performances are given by Brigitte HORNEY, who gradually freed herself from her involvement in the UFA era of the National Socialists, and Barbara RÜTTING, who shone with a brunette Doris DAY hairstyle.
Director Alfred VOHRER was able to attract another 1.8 million viewers to West German cinemas. However, that was less than the previous film, which had sold 2.6 million tickets. Nevertheless, both RINGER films are among the highlights of the West German Edgar Wallace film series.
