 Frustrated at the Warden s defiance, the people who want Lincoln dead decide to circumvent the penal process by enlisting an inside man to take Lincoln out himself. Headcounts keep requiring Michael to be back in his cell at regular intervals, and the interruptions are making it impossible for him to finish his work. Sucre tells him that the guards don t bother with counts when there s a lock-down, so he disables the air conditioner circuits on his next trip out. With the temperature rising, the cons start causing trouble, and a lock-down is announced. Unfortunately, tempers have already flared past the boiling point, and a riot breaks out before the cells can be closed. Oblivious to the chaos going on, Michael and Sucre go behind the wall together to work on drilling through one of the last walls to an abandoned sewer line. One guard, escorting Lincoln, gets caught by the prisoners and dragged back to general population. In the course of preparing to torture and kill the beaten man, Teabag (as well as the guard) inadvertently discovers the hole in Michael s wall. As the cliff-hanger episode ends, Michael is caught in a stand-off over who will make it out of his cell alive, while rampaging prisoners in the infirmary are about to break down the door into Dr. Tancredi s clinic.
