S1, E6: Every element of control at Hays State Prison feeds one central purpose: to keep convicted and dangerous felons inside. But when it all fails, two inmates make their move for freedom. National Geographic follows the intense manhunt for two escaped convicts. Inmates go into lockdown, tactical squads assemble and K-9 units scour the riverside looking for clues. Meet one of the best manhunters in the state and watch the shakedown as inmates are interrogated, cells are ripped apart and everything is searched.
