Suddenly, London goes dark and loses all of its electricity. There is commotion at a cinema, with people demanding their money back. The owner of the cinema, Karl Verloc (Oscar Homolka), enters through a back entrance to the living quarters above, and pretends to have been asleep and not know anything of the blackout. His wife, Mrs. Verloc (Sylvia Sidney) comes to get him and is surprised to see him, but he informs her that he had been sleeping the entire time.

Two bandits enter an express car, kill a messenger and open a box of valuables with dynamite; the others kill the fireman and force the engineer to halt the train and disconnect the locomotive.
