One night, Liam is arrested at a drug-laden party. He outrages the police due to his refusal to speak English, insisting he can only communicate verbally in Irish. JJ Ó Dochartaigh, a music teacher at an Irish-language immersion school, arrives to serve as an interpreter during Liam's interrogation. He helps Liam avoid charges and later hides a notebook of Liam's by taking it home himself.
JJ realizes that the notebook contains song lyrics in Irish and is impressed when he sets them to music. He approaches Liam and Naoise with the idea of starting an Irish-language hip-hop group. JJ convinces them that the music would be a way to bring the Irish language to an audience of Millennials and Generation Zers. Meanwhile, Liam begins a relationship with a Protestant girl named Georgia. Liam names the group "Kneecap", after the infamous punitive torture technique common in Northern Ireland during the Troubles.
The trio create a track together during an all-night, drug-fueled recording session. They start to perform live, and their music begins to draw crowds. JJ fears the damage to his teaching career that might result from a public connection with Kneecap's vulgar and blatantly political music. He decides to perform as the anonymous "DJ Próvaí", wearing a balaclava to hide his face during gigs. JJ also conceals his involvement in the band from his girlfriend Caitlin, who is heavily involved in the campaign for an Irish Language Act that would officially recognise the Irish language in Northern Ireland.
As Kneecap grow in popularity, they face controversy for promoting anti-social behaviour and outspoken republicanism in their lyrics. A dissident republican organisation calling themselves "Radical Republicans Against Drugs" (RRAD) threaten and attack Liam and Naoise. The garage containing Kneecap's recording studio and their recorded music is bombed, and the group believe RRAD is responsible.
With a tight deadline to produce a new track for RTÉ Raidió na Gaeltachta, the group break into the school where JJ works and record a song overnight. The song is initially banned from the radio due to its lyrical content, but after Dolores organises a protest campaign, the song is allowed to play and becomes a hit. However, with his identity as DJ Próvaí now public, JJ is fired from his teaching job, and Caitlin breaks up with him. After some hesitation, JJ decides to remain a part of Kneecap.
At a major gig, Kneecap publicly humiliate RRAD by playing an audio recording of its members demanding that Liam and Naoise turn in drug money over to them. In retaliation, an RRAD member in the crowd fires a gun and, in the ensuing chaos, Liam is apprehended and Naoise is captured by the RRAD. Police Service of Northern Ireland Detective Ellis, an Ulster Loyalist and Georgia's aunt, viciously beats Liam before confessing that she arranged for the studio to be bombed in an attempt to halt Kneecap's rise to fame, having previously warned JJ and Dolores of the damage it would bring. Meanwhile, the RRAD prepare to kneecap Naoise when Arlo arrives to kneecap the former himself. Arlo instead shoots three RRAD members and tells Naoise that he is proud of him and his music. He allows himself to be arrested while Liam is grudgingly released from police custody.
Kneecap's music becomes ever more popular despite the police and Detective Ellis doing everything in their power to stop them. Meanwhile, Caitlin continues her political campaign for the Irish Language Act, Dolores is shown singing in a pub (having overcome her agoraphobia), and Georgia and other students of all ages and backgrounds participate in an Irish language class.
