A U.S. Treasury agent (Yul Brynner, Kings of the Sun) and Scotland Yard detective (Edward Woodward, The Wicker Man and TV's The Equalizer) go undercover to infiltrate and tackle a brutal counterfeit gang known as the Golden Goose, raking in millions with their illegal activities. From Liverpool, the two men trace the Owl (Charles Gray, Blofeld of Diamonds Are Forever) to London where they hope to meet up with the mysterious gang leader Mr. Big. Veteran screenwriters John C. Higgins (He Walked by Night) and Robert E. Kent (Where the Sidewalk Ends) wrote this suspenseful thriller directed by actor/director Sam Wanamaker (Sinbad and the Eye of the Tiger) and co-starring Adrienne Corri (Vampire Circus, Madhouse).
