It's the Australian outback 10 years after the "end of the world". A loner (Guy Pearce) goes after a group of men who have stolen his car, a possession he's very attached to. After he sees them drive away he hops in the SUV they crashed and manages to get it unstuck from where they crashed it. He pursues, there's a high speed chase, and shots are fired. They eventually stop and he tells them that he's giving him back his car. They knock him unconscious and leave him by the side of the road. Undaunted, he begins his pursuit. Along the way he meets simpleton Rey (a great performance by Robert Pattinson), who recognizes the car he's driving as belonging to his brother. We find out that Rey was left for dead by his sibling--and he's understandably upset. So the loner now has a sidekick. They run into other people who are barely existing, get help from a vet who sews up Rey's wounds, and eventually find their way to the group of men.
The entire time I was watching this I wondered what the deal was with this car--is it worth all the problems trying to get it back? Then, at the end we find out what the importance is-- and it makes sense. Everything was out of proportion in him trying to get it back but you end up supporting the whole mess. THE ROVER could very well exist in the same universe as the MAD MAX movies, which I'm sure is a big influence. Recommended.
