A two-part mini-series following the police effort in the 1990s to catch serial killer Ivan Milat, who kidnapped, tortured and killed backpackers along the Hume Highway before disposing of their bodies in the Belanglo State Forest.

Six captive office workers are literally chained to their desks by a demented, escaped serial killer; former regional manager Thomas Reddmann (Redd). He assigns his ‘human resources’ the impossible task of proving his innocence or suffering gruesome consequences.
