Horror Vault's take

When a SWAT team moves a dangerous cartel kingpin through a county detention facility, the mission goes sideways in the worst possible way — an extraterrestrial invasion turns the lockup into a killing ground. Trapped inside with their prisoner and nowhere to run, cops and criminals are forced to set aside their differences just to stay alive. It's a relentless siege film that trades haunted hallways for alien carnage in a confined, pressure-cooker setting.
