Apocalypse Dog

Trawling across the arid desert of a post-apocalyptic world in their ramshackle car, a survivor, Bob and his dog, Pasha, realise they are in need of sustenance. In the distance, they spy what looks like a city that has survived the destruction. Upon closer inspection they discover an oasis in the desert. Looking for a quick easy meal, Bob discounts the oasis and walks back to the vehicle, only to find that Pasha has sensed something within the island of green that may be the answer to their prayers.
