Conniving Broadway starlet Mida King (Patricia Dane) has plenty of enemies, so when she's found murdered at Grand Central Station, Inspector Gunther (Sam Levene) calls together a slew of suspects for questioning. Mida's shady ex-flame, Turk (Horace McNally), seems the most likely culprit, but when smart-mouthed private eye Rocky Custer (Van Heflin) -- also a suspect himself -- begins to piece together the crime, a few clues that Gunther has overlooked come to light.
