While getting a signed confession from a possible suspect after the skeleton of a dead Navy Lieutenant is found in a forest, McGee's interview at the prison takes a turn for the worse when a guard stumbles in, dead, triggering a riot with the inmates responding by taking a few guards as well as McGee himself hostage. The inmates only have one demand: they only want the murderer, not all of them to be brought to justice. Gibbs, Tony, Ziva, Abby and Ducky must race against the clock as well as the prison warden's deadline to find out who's truly responsible and save McGee before it's too late.
