The Legion of Missing Men is a 1937 Monogram Pictures film about the French Foreign Legion set in the French protectorate of Morocco. Directed by Hamilton MacFadden, it stars Ralph Forbes who had also served in the cinematic Foreign Legion in Beau Geste (1926) and Beau Ideal (1931). Singer and actress Hala Linda was married to Richard Gump, the composer of the film's "The Legionnaires Song". It was the only film of Monogram's Marlene Dietrich imitator. The film features scenes reused from a silent film, presumably Under Two Flags. Plot Bob Carter is a professional soldier of fortune whose expertise is in the use of the machine gun. He has plied his trade for Sun Yat-Sen in the Xinhai Revolution, the Mexican Revolution and with the Spanish in the Rif War for de Rivera. Now he is content to be a Legionnaire in the 20th Marching Company of the 3rd Foreign Infantry Regiment with his comrades in arms the American Muggsy and the Englishman Bilgey. Bob's world changes in a variety of ways. First half his company is lost in attacks by Shiek Ibrahim-Ul-Ahmed's insurgents who capture the company's cargo of crated machine guns and ammunition. Fortunately for the Legion the weapons are disassembled and none of the Shiek's band has the knowledge to get them into working order. Granted leave in the town of Zabala, Bob is romantically pursued by Nina De Bernay, a French nightclub singer. Nina entertains the Legion but is romantically pursued herself by Bob's Sergeant Garcia; however Bob believes Nina to be his Sergeant's woman and does not pursue her. Arriving with a draft of replacements for the 20th Company is Bob's own younger brother Don who admires Bob's carefree action packed international lifestyle. Initially upset that Don has thrown away his university education and business potential away, Bob soon resigns himself to his brother's company. Problems arise when Nina, who can not have Bob and doesn't like Sgt Garcia makes a play for Don. Immature and oblivious to local custom and military disclipine, Don strikes Sergeant Garcia who gleefully has him arrested and vows to send him to the dreaded Penal Battalion. Bob breaks the chain of command to appeal directly to his Regimental Commander to avoid ruining Don's life and the Colonel allows Don's release. Unknown to all, Nina uses her friendship with Shiek Ibrahim-Ul-Ahmed to have two of his men free Don
