Sabotage hits the London docks by communist’s intent on crippling the British economy and enabling subversive forces to undermine the government. The police suspect a foreman, he appeals to his secret co-conspirators for help, but they kill him off. The police track the saboteurs to a London business college, and suspect an MP might be involved. They are, however, unaware of the saboteurs plans to blow up the country’s major power stations until one of their group, shocked by the foreman’s murder, squeals. The film culminates in a gun battle at Battersea power station.
