After his release from prison, an inventor develops an eerie purple light that renders him invisible, enabling him to seek revenge on his unfaithful wife and his crooked business partner.
Film historian Scott MacQueen cited "The Vanishing Men", a treatment West had targeted for film in 1921 as the inspiration for the film. The film was adapted from a stage play which was written by Roland West and Carlyle Moore. Comedian Johnny Arthur made his feature-length debut in The Unknown Purple.
