Convicted murderer "Turk" (Stephen McNally) escapes from police custody, crashing through a washroom window as a train pulls into Grand Central Terminal in New York.

Other suspects are rounded up: Mida's greedy phony psychic stepfather Ramon (Roman Bohnen); her ex-husband Paul Rinehart (George Lynn), who works at the terminal; and her producer Frankie Ciro (Tom Conway).

Then Roger Furness (Samuel S. Hinds), Connie's magnate father and chairman of the board of the railroad, shows up to guard his daughter's interests.

Frankie finds her, but she calms his anger at the prospect of losing the star of his expensive production by telling him that she plans to get a rich divorce settlement in about six months, more than enough to finance an even more lavish show.

Rocky identifies the man as Roger Furness, who breaks away and jumps aboard a departing train, but falls to his own death on the third rail.

Cast notes Grand Central Murder is a sequel of sorts to Kid Glove Killer, in which Van Heflin played a similar part.
