Directed by Henry Hathaway, Secretary tries to help her boss, who is framed for a murder. An ex-convict who returns to the private detective business upon his release. Sour and surly, Galt behaves himself only when he’s around his faithful and adoring secretary Kathleen. When Galt’s crooked former partner Tony inaugurates an affair with socialite Mari, Cathcart’s waspish art-collector husband arranges Jardine’s murder, carefully pinning the blame on Galt. On the lam from the cops, Galt must rely on Kathleen to help gather enough evidence to prove his innocence.
