Teenage misfits Microbe (Ange Dargent) and Gasoline (Théophile Baquet), one nicknamed for his size and the other for his love of all things mechanical and fuel-powered, become fast friends. Unloved in school and misunderstood at home—Microbe is overprotected, Gasoline is by turns ignored and abused—they decide to build a house on wheels (complete with a collapsible flower window box) and sputter, push, and coast their way to the camp where Gasoline went as a child, with a stop along the way to visit Microbe’s crush (Diane Besnier).
