When fate brings Belfast teacher JJ into the orbit of self-confessed "low life scum" Naoise and Liam Óg, the needle drops on a hip-hop act like no other. Rapping in their native Irish, they lead a movement to save their mother tongue.
Local police officer Sergeant PJ Collins is a gentle man who hides from people and fills his days with comfort food and half-hearted police work. He is one of life's outsiders, lovable, but lonely and a bit rubbish at his job. When the body of long-lost local legend Tommy Burke is discovered, PJ is called to solve a serious crime for the first time in his career. Unearthing long buried secrets, PJ finally connects with the village he has tried so hard to avoid.
