Prison Star

Among the stars, a space train glides silently toward a distant steel orb — another delivery of prisoners to the prison star. Sections of the orb are controlled by armed prisoners, divided into rival political groups and gangs, with a secure area for the guards and administration. Among the latest arrivals is an engineer. He is chosen to solve the problem confronting the prison: the orb is rapidly filling up with waste. But no one seems willing to help him.
