Ships have been disappearing in Quandon Sector, and the Commandos identify the planet Omrai as the probable site of the problem. They planet secretly and nearly fall victim to the world’s cold and formidable wildlife before making contact with a local man, who tells them of a large ship that wrecked there years before, and the strange disease that fells those they enslave. Connor investigates and discovers that the ship is an Arcturian battlecraft, and that their captives apparently die when they break free of their form of mind control. Vessels are being captured, brought to the planet, and stripped to re-outfit the battleship, which is nearly ready to lift and return to a War that its crew cannot possibly know has already ended. To succeed the Commandos must stop the "mind slaver."
