Frenetic crime fighting antics from Paul and Steve Temple.
A scientist (Andrew Leigh) is kidnapped by the mysterious criminal Z. The scientist's daughter (Anne Hayes), a friend of Steve (Dinah Sheriden), asks for help but she is later found dead. Paul Temple (John Bentley) and Steve begin to investigate, their search taking them into the countryside but where Z's organisation seems to have agents everywhere...
A fast moving film that stretches a small budget as far as it can go, unfortunately a lot of the film takes place in hotel rooms or driving around country lanes (though Temple drives an early Aston Martin which is interesting). The film is based on a radio serial and has that feel with regular cliff hangers. Basic but effective.
