Each contest occurs at night, as three contestants take part in gory and unpleasant challenges to find (or release) a key.
After each successful round, one of the contestants has to run a floodlit course pursued by snarling dogs. They are given a head start, which reduces in length the longer the contestants take to pass each task (the countdown begins with 160 meters). The contestant carries a red backpack containing several thousand pounds, which they keep if they successfully reach the end of the course before the dogs catch them.
The show purported to take place in a haunted country estate in the English hills [but] the filming was transferred to Eastern Europe
