Caged

While investigating the murder of a dead marine whose skeleton was found, McGee heads to a women's prison, hoping to retrieve a written confession from her, but all hell breaks loose when the inmates riot and take over the prison. A guard is killed during the riot and the inmates want only the murderer, not all of them to be brought to justice, holding McGee and two guards as hostages. The warden issues a deadline of before sundown during which he'll retake the prison by any means possible, forcing Gibbs and his team to race against the clock to not uncover the true identity of the murderer but to also save McGee's life.
