Riots, Drills and the Devil (1)

Since Scofield's transfer was cancelled, the woman in Montana tells Kellerman to take care of Burrows quickly. He has an informant call an inmate in Fox River to kill Lincoln. The only form of identification of the inmate is an elastic bracelet. Veronica (Robin Tunney) avoids Nick Savrinn, until she realises that he is trying to help her all along, when he hears that the anonymous phone call to arrest Lincoln came from Washington D.C.

This is vital to his escape plan as the wall prevents the team from entering a pipe that will take them to the infirmary. Meanwhile, after Lincoln is ambushed by T-Bag and his men, he holds new CO Bob Hudson hostage, who tries to escape, but T-Bag takes him to Michael's cell, where he learns of the escape pla
