Vincent Floyd, a seeming lazy figure lounging around London Gentlemen's Clubs is in fact a secret agent hot on the trail of Michael Marlowe whom he suspects of smuggling drugs into Britain from France on a regular basis. Floyd has so far struggled to gain evidence on Marlowe, but through a series of incidents finds himself bound for Paris on the same plane as Marlowe. Marlowe succeeds in doping Floyd and taking him to his underground hideout beneath a Parisian back-alley nightclub.

With the help of Marion, a young woman who has been working for Marlowe, Floyd manages to escape the flooding dungeon linked to the River Seine which he has been trapped in. He flies back to England, pursued by Marlowe's gang and manages to avoid the attempts of his enemies to crash his plane. In a final confrontation, Floyd pursues Marlowe's car in a plane and prevents his escape.

The film was based on a successful West End play of the same title by Arnold Ridley and Philip Merivale, who then adapted it into a screenplay. It was made by British International Pictures at Elstree Studios with sets designed by art directors Clarence Elder and John Mead. Originally Leslie Howard had been intended to star, but instead the role was given to the lead in the play Henry Kendall. Filming began in December 1930,^[2] and included large amounts of location shooting. Both the director and the star, Kendall, were able to fly during filming scenes. Co-operation was received from Imperial Airways, the French Air Union and the De Havilland Aircraft Company for the aviation sequences.
