Making a delivery to a mysterious mansion in a rainstorm, radio salesman Hank Martin is knocked out when a suit of armor topples on him. Upon awakening, Hank finds himself in the time of King Arthur. At Camelot Castle, Hank uses a cigarette lighter and his skill with a lasso to save himself from being executed as a demon. Hank so impresses Arthur that the king orders him to joust with one of his knights to save the life of Princess Alisande.
