Crooked lawyer Lom is being pursued by the Ringer, a master of disguise who holds Lom, his former partner, responsible for the suicide of his sister. While the police try to protect the terrified Lom, the Ringer appears before Lom and reveals himself to be police doctor Wolfit. He
strangles Lom with a wire from the burglar alarm, then escapes. Old-fashioned melodrama with an excellent cast.
