Ex-soldier Troy Poe inherits a corrupt private prison and goes inside undercover as an inmate to expose the people behind it. When the head guard he trusted turns out to lead the crime ring, Troy has to prove he is the owner, not a prisoner, or break out, while protecting an old inmate whose sentence was falsely extended and a doctor caught in the middle.
