The chaos begins in Brooklyn. Jonesy (Bud Abbott) and Max (Lou Costello) are wrestling promoters whose star fighter runs out on them. Following him to Aldiers, they get more than they bargined for when they're tricked into joining the Foriegn Legion. A hot time follows as the comedians - still looking for their fighter - foul up basic training, dodge desert cutthroats, and chase pretty slave girls. (At an auction, Max wonders if he can buy them at $1.25 down and $1.00 a month.)

No opportunity for excitement is missed. There's a beautiful French spy (Patricia Medina), a traitorous legionaire (Walter Slezak), and plenty of local color, from Arabian horsemen to dancing girls. As for Abbott & Costello, both stock and new comedy situations make the most of their talents. Wether it's a mirage or an oasis watched over by an alligator with false teeth, it's a setup for humor - which they deliver in their customary style.
