This rollicking sports comedy from Finnish director Markku Polonen follows the exploits of Seppo 'Sladi' Pesonen, an ex-top-tiered race car driver now reduced to instructing students at a driving school. To relieve the monotony of this undesired career, Pesonen builds "Team Susan," a road rally team based at Pekkarinen's Garage in the Finnish countryside. Soon, Sladi's nephew Luumu arrives from Helsinki and learns of the team, his enthusiasm skyrockets and he hops on board with the assist of mechanic Suko. Yet the men encounter Machiavellian sabotage at the hands of the vile Torppo, the owner of the lot that contains Pekkarinen's Garage, who is determined to interfere with the plans of Team Susan.

Luumu håller på att glida in på en kriminell bana, men får jobb hos sin farbror, som är en f.d. rallyförare. Nu driver de byns bilskola, café och verkstad och alla i byn väntar på den årliga rallytävlingen. Luumu får tillfället att visa sina talanger och tävlingen blir en dramatisk tillställning där mycket står på spel.
