The truth of the island
Righty-ho then. Robbins escapes the island determined to tell the authorities all about the naughty savagery that's going on there, but why would they care?
The government has outsourced their prisoners to this private penal company precisely because they want to wash their hands of them. I doubt very much they'd be concerned with how humanely they were being treated. After all these are the same people who killed thousands of innocents and then covered it up during the conflict Robbins took part in at the beginning of the film.
I found it quite difficult engaging and staying focused throughout this low budget, low quality offering so I may well have missed some vital plot element here. If so please point it out.
