Mach GoGoGo

Synopsis

The elderly son of a deceased gangster drives a Model T that contains a code for a missing haul of stolen money, a haul that Tongue Blaggard, a brutal gang leader, is determined to find. During this episode, Speed attends a road racing school where Racer X - the Masked Racer - suddenly appears, wheels the Mach 5 through a tricky slalom course, and thus intimidates the other drivers and the school instructor, but not Speed; Racer X also chances upon Pops, Mom and Speed, all remembering Rex and saddened in wishing he would return - a wish Rex quietly vows to someday keep. Speed Racer, Spritle, and Chim Chim go out for a test drive for the Mach 5. The radio makes an announcement that Tongue Blaggard made an escape from prison. The Racers meet a girl and her grandfather whose Model T racing car broke down on the road. Speed offered to help out, but the old man declined. Later on, the racers find the broken down Model T again. Now the old man changes his mind, and accepts Speed's help. While the Racers dine with the old man with his granddaughter and his adopted children, Blaggard steals the Model T racing car, hoping that it once belonged to the crook, Lightfingers Clepto. With the car stolen, Speed vows to bring back the stolen car back. Trixie in her helicopter spots the stolen Model T and brings it into Pops' garage for minor repairs. On his hideout, Blaggard recalls his encounter with the inmate who told him about the Model T vehicle's secret engine number that leads to the loot. Making a decision to bait Blaggard, Speed adorns the Mach 5 using a flag to bear the engine's secret code. Blaggard's men follow him while a cargo helicopter flies ahead. The thugs set a fire on Speed and the old man, until Racer X arrives to defend his brother. Instead, he ends up on the edge's cliff. The helicopter lowers a ramp to unload a squad of weapon-carrying motorcyclists.
