Two young boys, both training hard at a karate studio, take time off to travel with their grandfather in his RV. What was supposed to be a camping and fishing trip turns into an adventure when they come across a rich family in danger from some hillbillies. It seems the hillbillies have taken a liking to the rich family's fancy RV and have kidnapped the daughter to gain access to it, so our young martial artists must rescue the girl and put a stop to the hillbillies' plans.
