Rogue's March was described by one observer as an eastern western. A mustachioed Peter Lawford stars as Capt. Dion Lenbridge of His Majesty's Service. Branded a traitor, Lenbridge is cashiered from the regiment. In fact, Lenbridge isn't a traitor, but he spends the next 84 minutes proving it. He makes it his mission in life to rid India of the insidious influence of Russia, whose leaders intend to establish a stronghold in the Jewel of the British crown. Though the Russians depicted herein are of the Czarist variety, they spout curiously communistic dialogue, a reflection of the Red paranoia then prevalent in Hollywood. With the grudging assistance of Captain Thomas Garron (Richard Greene), Lenbridge valiantly thwarts the rascally Russians' schemes during a climactic desert battle. Janice Rule is on hand as the nominal love interest, while Leo G. Carroll does a C. Aubrey Smith routine as Lenbridge's stiff-upper-lip father.
