Directed by Rich Peppiatt — Screenplay by Rich Peppiatt.

Writer-director Rich Peppiatt’s Kneecap tells the story of the rise of the real-life Belfast-based Irish hip-hop group known as ‘Kneecap.’ In Belfast, we meet Liam Ó Hannaidh (played by himself) and Naoise Ó Cairealláin (played by himself), two young men who have been raised on the beliefs of an Irish republican, Arlo (played by Michael Fassbender), who has faked his own death to avoid being caught by authorities. When, one day, Liam is arrested after attending a party where drugs were being widely spread, he refuses to speak English to the authorities opting instead to speak Irish Gaelic, which frustrates the protestant authorities. Therefore they reach out to JJ Ó Dochartaigh (played by himself), a music teacher at a school that teaches Gaelic, so that he can translate the conversation at the station as an interpreter. Following this encounter, JJ, Liam, and Naoise get together to record Irish Gaelic hip-hop, perform it, and bring attention to the language that they feel is not properly recognized. This all happens at a moment in time when JJ’s girlfriend, Caitlin (played by Fionnuala Flaherty), is getting into politics to campaign for an Irish Language Act.
