Arrest Bulldog Drummond

Bulldog Drummond is summoned by eccentric scientist Richard Gannett to his London home after finding him murdered and his electric "death-ray" device stolen. The Scotland Yard investigation puts Bulldog Drummond (John Howard), Algy Longworth (Reginald Denny), and Tenny (E. E. Clive) at the center of suspicion, but they soon uncover a web of deceit and espionage involving spy Rolf Alferson (George Zucco). As Bulldog delves deeper into the mystery, he enlists the help of his fiancée Phyllis (Heather Angel), and together they unravel the conspiracy to stop Alferson's nefarious plans.
