In this thriller, an American visits England and finds himself entangled with international spies after they kidnap a famous scientist and he ends up with a briefcase containing a secret formula. Rather than call the Yard, the fellow decides he will solve this by himself. But it is too much for him and eventually he teams up with the Yard inspectors and the case is solved. ~ Sandra Brennan, All Movie Guide
