Mike (Wentworth Miller) entered the most dangerous prison in Panama, SONA, to help Sarah take the blame. It is a place where some serious criminals are detained. Because the prisoners rioted a few years ago, the local army has completely withdrawn, leaving the prisoners to fend for themselves.

They asked Mike to help them complete a task, which is to find and rescue the Australians in SONA within a week. For the sake of his beloved woman and nephew LJ, Mike and Lincoln, who was outside, started their new round of prison escape plan!
