The tale begins in Sydney. Wade(Wiese) and his girlfriend, Lisa(Lofberg) get a car and are going to drive around Australia. They are arguing. They visit a beach and Wade gets stung by a jellyfish. Lisa wants to go to Ayers Rock. They drive to the outback and their GPS sends them into the middle of nowhere. They are in the desert. Lisa wants to head back to the main road but Wade says that they are going on. The GPS keeps rerouting them and they get lost. They find time for some chatting about their relationship while this is happening. They decide to walk to a ridge to see if they can spot a way out. It begins to get dark so they can't drive until the next morning.
