Haunted by the ghosts of the past, lone traveller Ronin wanders the post-apocalyptic wastelands in search of his father’s killer. The devastation caused by climate change led to a global nuclear war, destroying civilisation as we know it: lands are scorched and cities destroyed. Electrical equipment no longer works and gasoline has long lost the properties that made it the world’s greatest resource. The main currency in this new world is AK47 cartridges. Everywhere Ronin goes, he encounters blood-thirsty headhunters and rogue gangs all fighting for scraps in this dangerous new world. Then, one day, Ronin meets a wayward teenage girl who offers him a precious bounty for escorting her to her birthplace, a journey that will require all his fighting skills.
