Fate brings together disillusioned music teacher JJ with self-confessed 'low-life scum' Naoise and Liam Og, changing the sound of Irish music forever. Under the name Kneecap, the band begins molding the language to fit their tough, anarchic, hedonistic lives. To get their voices heard, the trio must overcome police, paramilitaries and politicians as the future of the Irish language erupts into the public arena - with them at the center. Yet their worst enemies are often themselves, as family and relationship pressures threaten their dreams, and their illegal exploits draw condemnation from all sides.
