Marvin is a somewhat dorky 8-year-old kid with a lot to prove. The bullies at school taunt him, his friends are not very helpful, and all he wants is to just belong. So in an attempt to solve his problems, Marvin gets an idea: Karate lessons! But even with a master sensei and a new gi, is Marvin destined to a life in Klutz-ville, or will he emerge Karate Cool and ready to take on all of William Clarke Elementary?
