The Door to September

When office manager John Summers falls through a portal, he lands in an alternate universe that resembles prehistoric Earth. Beside him is Liz from Accounting. The sun sets, and the temperature plummets. Unwittingly, the pair take refuge in the empty lair of a predator with long fangs and an even longer memory. Armed with nothing but a blunt cutlery knife and paperclips, John and Liz struggle to survive in the wilderness. But hunger, cold, and vicious animals are the least of their problems. Just wait till they meet the natives.
