Kim is a strange young misfit who was just a little girl when her father was murdered. After his death, her mother Tina spirited her away to a remote life off-grid in the Scottish wilderness. Fearing for her safety, Tina trained Kim in combat and kept her from the outside world with exaggerations and lies about the dangers of modern life.

Now 21, Kim’s determined to experience everything she’s missed out on and sets off into the real world on a secret mission to honour her father’s memory. Things get complicated when she meets hapless brothers Nicky and Jay. When a drunken prank goes spectacularly wrong, Kim’s rush to exact her revenge ends in violence. Bound by the mess they’ve created, the trio set in motion a chaotic series of events that puts all their lives in danger. Hunted by the mysterious Brooks and Thompson, associates of crime boss Jimmy Davies, Kim must reunite with her controlling mum if they are all to survive.
