Survival horror in which five strangers are kidnapped and held inside an underground dungeon, where they are given plenty of water but nothing to eat. As their hunger grows, the instinct for self-preservation comes to the fore - and as time passes some members of the group resort to the unthinkable in order to survive. As events unfold, it gradually becomes clear that they are the subjects of a sinister experiment by a scientist (Bjorn Johnson) with very personal reasons for his fascination with the extremes of human behaviour.
