Bulldog Drummond discovers that a gang of thieves are stationed in a house located in his part of town, and he determines to capture them. Headed by Blackton, they have doublecrossed their previous companions in crime, one of whom is known as The Masked Strangler. Patricia Verney takes a position as secretary to Backton, who killed her uncle and robbed him of some emeralds. Though Blackton employs various fiendish ruses to safeguard the jewels, Drummond and his men from Scotland Yard unmask the strangler and bring the criminals to justice.
