Mastrone schemed with the warden to set Leone up in the film Lock-Up .
Dallas offers to help Leone escape to warn Melissa but instead delivers Leone right into Drumgoole 's hands where he finds out that Drumgoole wanted him to try to escape so he would receive a mandatory 10-year sentence for the second escape attempt and the inmate who was going to rape Melissa was just a corrupt prison guard called Mastrone who was part of the wardens scheme to set Leone up.
