They call them Rovers – aimless wanderers living on the fringes of society in the vast Australian outback, looking to escape their pasts and start anew. Buzz has been to damn near every corner of the continent searching for the legendary Strays Gold – a haul that will keep him in parts and petrol for the rest of his days. But, just as he is ready to give up, Buzz is approached by Eric, who has come into possession of a map to Strays Gold. Eric is happy to part with the map in exchange for passage – he and his activist friends Tori, Skye and Tom want to stage a protest at the site of a new mine from mega mining company Madsen Minerals, headed by nefarious billionaire Daniel Madsen. To get to the mine unseen, they must travel through the impenetrable Mamuya Valley. Seeing this as his last chance to fulfil his dream, Buzz convinces his ragtag crew of Rovers to follow him on one last quest for the lost gold. With their modified off-road rigs piled high, the Rovers and Activists embark on the greatest adventure of their lives. But soon tensions rise and ulterior motives are revealed with exciting off-road chases, daring rescues and amazing discoveries to follow.
