Synopsis by Sandra Brennan
This suspenseful crime drama features cameo appearances by some of Great Britain's more popular pop groups of the mid-1960s as it tells the tale of an ex-crook who finds success managing several of the groups. The trouble begins when a master jewel thief blackmails him into becoming a gem smuggler. Together, they set sail across the Channel to get a fortune in diamonds safely to Amsterdam. They are pursued by two determined detectives.
