In a post-apocalyptic world, where water and gasoline have long since dried up, a prince from the oasis (one of the last known safe havens) must venture out to find medicine for the ailing queen (Lucy Liu). But along the way, he gets mixed up with a warlord (James Franco) and his robot Ash (Suki Waterhouse), which leads to a daring journey through the desolate wastelands.
