During the final days of the term, Dr. Chezko, an engineer and old friend of Speed Racer's, arrives with a chamber that will finally run the Mach 6 on purely natural energy - its final piece - and asks Speed's permission show it off to the academy. Zile, returning undercover as a janitor, works with Annalise to steal the chamber and embarrass Speed by replacing it with a double. Meanwhile, Spritle plans a family bonding trip to his camping retreat for the break.
