Change Guy

It's nature vs. nurture when a nerd swaps bodies with the toughest guy in school! Tuji and Usoo have swapped...their bodies! After becoming the subjects of a mad scientist's experiment with her latest invention - the quantum teleporter - their bodies are switched, leaving only their minds and spirits intact. Usoo, who was once a model student, must face the life of Tuji, a teenage menace. Never having an enemy in his life, he now has to deal with the handful of Tuji's list, but will his kinder, gentler demeanor ward off his rivals? Or will survival determine his future? Will he become the hardened fighter that matches his new exterior?
