The Black Gang

Although the First World War is over, it seems that the hostilities are not, and when Captain Hugh "Bulldog" Drummond discovers that a stint of bribery and blackmail is undermining England's democratic tradition, he forms the Black Gang, bent on tracking down the perpetrators of such plots. They set a trap to lure the criminal mastermind behind these subversive attacks to England, and all is going according to plan until Bulldog Drummond accepts an invitation to tea at the Ritz with a charming American clergyman and his dowdy daughter.
