Furious that the work on his car is taking too long at the mechanic’s, Dan storms into the shop with Chris for sweet, sweet revenge. However, what they uncover is more than they ever imagined. The Mechanic, facing bankruptcy, had been removing parts from Dan’s car to build a large robot for use in an underground robot fighting ring! Since the only way to get his car fixed is to save the mechanic’s shop from going out of business, Dan builds his own giant robot suit and enters the fighting ring himself to save the day. But when his fight opponent turns out to be Elise in her own robot suit, Dan soon learns that he might be in over his head!
