While the Flathill Army soldiers set the Mach 5 aflame, Speed attacks one of the rebels. The General announces that he ordered Ali Ben Schemer, his cousin, to blow up his son's racecar because they need his help in the revolution. When Kim notes that his special brakes can never be repaired, Schemer suggests that Kim and Speed race without brakes. The next morning, Schemer gives them a sack lunch and the race begins. He then takes Trixie, Spritle, and the General prisoner. Chim Chim rescues Spritle and they escape on a camel. Meanwhile, as the Black Tiger and the Mach 5 race through the desert, the sack "lunches" open revealing deadly scorpions. Kim realizes what Schemer is up to. The scorpions are smashed; the race resumes.

Later, members of the Flathill Government Army, who are after the rebels, rescue Spritle and Chim Chim. Back on the racecourse, the Black Tiger is devoured by quicksand. Kim, Speed, and the Mach 5 almost meet the same fate.
