Matt, Axl, Duff and Saul live in a universe where rock music is the center of everyone's daily life. Their dream is to become a professional rock band, unfortunately for them they have no money for proper equipment and not only that, they lack the necessary experience. On a day like any other, their attempt to make it big, is crushed due to a failed robbery, a mysterious house and a psychologically disturbed demon. This creature then forces Matt and the others to participate in the Rock Warriors Tournament, a legendary and bloody competition where musical instruments become weapons and where dragons, crazy metal-heads and dirty hits are permitted by the Tournament Regulation!
