Captain Holling is relieved of command of his ship after he suffers a nervous breakdown. His alternative, Captain Downey, takes over the liner simply as it’s about for use for an experiment in distant management. Professor Grimson has devised a system for controlling the ship from a laboratory on land. However as Grimson demonstrates the system and the particular element that makes it work, a rival group is listening in, hoping to make use of the machine for its personal functions. Shortly after the demonstration, the professor is attacked and fatally injured. Main Pope comes on board to research the assault, and he decides to return alongside on the deliberate journey. Quickly the ship is filled with passengers and crew–and at the very least two of the ship’s occupants are actually enemy brokers.
