The year is 2025, the place Mars. Humans have been mining the red planet for a number of years without event, but it becomes clear that they are not alone and that the original inhabitants are as pissed as hell. A small squad of police are sent to apprehend dangerous criminal "Desolation" Williams but soon find themselves forced into an uneasy partnership in a desperate bid to survive Mars' dark and malevolent spirits. A 'Mars Bar' is a sickly sweet confectionery that provides no form of nourishment other than an ultimately detrimental sugar hit and retails at about 35 pence, a piss poor analogy for this movie I'll admit, but you get the flavour. John Carpenter.......what the F**!*K happened?
