PLOT:
In a far future world, the former gladiator Delos wanders the waste with a young, ethereal spirit named Prome. The two end up in the middle of the desert, where Delos is captured by a group of half-beetle people who force him to fight for his life. Delos wins both the fight and their favor, but soon they all find themselves under threat by a far-off empire with a towering, all-consuming colossus.
