When the skipper dies while a fire rages unchecked, it's up to First Officer Jack Holt to assume command, send the passengers away from the lifeboats, and save the ship. The company is grateful and he gets his fourth stripe, but not a command; as Second Officer he was in charge of the cargo lading, and someone snuck gunpowder into the hold. But an opportunity comes his way when some fellows offer him a ship on its way to Valparaiso. What he doesn't know is that they're planning to scuttle the ship en route for insurance, and that his wife, Grace Bradley, has been making advances on his third mate, Robert Armstrong, and anything else in pants.
It's Holt at his most forthright hero type, knocking down growling members of the black gang, and chopping holes in lifeboats when the mutineers want to flee. It's prime Second Feature work from director Lambert Hillyer. There's Charles Murray as his Chief Engineer, adept at taking anything mechanical apart..... but unable to get it back together. With Diana Gibson, Guy Usher, Dewey Robinson, Edwin Maxwell, and Billy Gilbert.
