"Mystery Liner" was originally released back in 1934.
Anyway - As the story goes - Captain Holling is stripped of his command after a nervous breakdown. When Captain Downey assumes command, he discovers that the ship will be navigated by a remote-control device invented by Professor Grimson. A gang of villains has figured out how to intercept signals from the device and assume control of the ship. Murder, mayhem and suspicion ensue.
