Shawshank Ridonc-tion

'''The teams travel to one of the most dangerous prisons in Australia, where they must escape and float down a river to the next Chill Zone. Someone is determined to win to be able to speak to someone, but in the end gets dumped by their love, leaving an opening for a doubter to work with; while two rivals finally bond with one another. Meanwhile, the four greatest rivals end up trying to take down each other, only to work together in order to survive their ordeals. While one squad appears to have the upper hand, the other gets another shot through a non-elimination.'''
