While drowning his sorrows at the local bar, blind writer Phillip Hannon (Van Johnson) eavesdrops on a nearby conversation. Convinced that he's just overheard details of a kidnapping plot, Hannon runs to the police. When they dismiss his suspicions as the ravings of a blind man, Hannon takes matters into his own hands. With the help of his ex-fiancée, Jean Lennox (Vera Miles), and his loyal secretary, Bob Matthews (Cecil Parker), Hannon uses his four remaining senses to track down the criminals.
