Portal

What would you do if you woke to find every living soul had disappeared? Freak out, or man-up and do something? Strangers Nate and Casey need to decide what to do, where to go next, and what those mysterious portals are. They also want to find out who has caused whatever it is to happen. But they might not like the answer, as New Zealands military wants them dead. They simply shouldnt be here, in this alternative universe. In a David vs Goliath battle, Nate, Casey, and a dog called Kevin take on military forces in a bid to get home - wherever that is.
