Flash forward several years when the prison is reopened, under the control of its new warden Eaton Sharpe, a former security guard who framed Charlie.

Trivia, insights & behind the scenes
This was Renny Harlin's first American film after Finnish cult hit Born American; it bombed so hard he got fired from directing Alien³ before redemption with Die Hard 2.
Shot in an actual decommissioned prison in Rawlins, Wyoming—cast and crew swore the location was genuinely haunted, which honestly tracks.
