During the demonstration of a device which allows the observation of alternate dimensions, an accident causes the building in which the demonstration is taking place - and its occupants - to be transported to a dimension seemingly devoid of animal life but for large, vicious carnivores which hunt and kill the displaced humans one by one. The chance of discovering intelligent non-human life splits the group's priorities between exploration and survival, but limited resources and a diminishing window of opportunity to escape this ferocious planet forces disgraced Colonel Synn into a desperate gamble to repair the device which can send them home. The group is picked off one by one until only Colonel Synn, Dr. Karen Frost, and Dr. Jillian O'Hara are left. Colonel Synn and Dr. O'Hara manage to repair the device and return home, but sadly, Dr. Frost is left behind and is presumably killed by the monsters.
