Kenneth Harlan stars as the enigmatic Mr. Tiller, who may or may not be a notorious jewel thief. Eluding both criminals and the authorities alike, Tiller manages to restore a packet of valuable gems to their rightful owners. He also orchestrates the reformation of a fledgling gang moll, played by Ruth Clifford. The direction for Midnight Madness was credited to Rupert Julian, but the trade magazine Variety doubted this, noting that the film was far below Julian's usual standards. In this instance, however, Variety was wrong: Substandard though it may have been, the film was definitely a Rupert Julian production, and was in fact a sequel to his 1917 effort The Mysterious Mr. Tiller.
