Dangerous Cargo

Most of the story takes place on a cargo ship, slowly inching its way through treacherous waters with a cargo consisting of a top-secret poison gas. When the ship's intoxicated doctor reveals the nature of the cargo to a good-time girl in a foreign port, chaos ensues, culminating in the death of the treacherous doctor at the hands of the ship's three commanding officers: Englishman Falcon (Kim Peacock), Frenchman Lestallieur (Walter Rilla), and Russian Tomasov (Robert Newton).
