A man accused of a crime he has no memory of committing must survive incarceration long enough to stand trial in this brutal drama featuring Pete Postlethwaite. In the aftermath of a drunken one night stand, Ben Coulter (Ben Whishaw) awakens hung-over and bloodied, and lying next to the dead body of a young woman. Every shred of evidence indicates that Ben is the killer, but if that's the case how is it that he has absolutely no recollection of such a brutal crime? Thrown behind bars until the day that he will stand before a judge and jury, Ben discovers that the strong survive in prison, and the weak often perish. Should he somehow manage to live long enough to have his day in court, odds are good Ben will wind up right back where he is, in the middle of a sadistic nightmare from which he can not wake up.
