When fate brings disillusioned music teacher JJ into the orbit of self-confessed ‘low life scum’ Naoise and Liam Óg, the sound of Irish music is changed forever. Under the name Kneecap, their band begins moulding the language to fit their tough, anarchic & hedonistic lives. A language encumbered with forty words for stone now has one for stoned.  

But to get their voices heard the trio must overcome police, paramilitaries & politicians as the future status of the Irish language erupts into the public arena – with them at the centre. Yet their worst enemies are often themselves, as family and relationship pressures threaten to pull the plug on their dreams.
