By Whose Hand?
On the night express train from Los Angeles to San Francisco everyone’s a suspect when a jewelry magnate is found stabbed to death and an escaped killer is feared on board. It’s up to newspaper reporter Jimmy Hawley (Ben Lyon) to unravel the secrets of the motley group of passengers and find the killer before he strikes again in this tense and atmospheric whodunit.
