The plot unfolds through several escalating turning points:
- The False Flag Operation: Agents from the Department of Internal State Security (DISS), led by Walter Gassman, execute two police officers in a patrol car and leave their bodies inside District 13 to incite gang retaliation and public hysteria.
- The Framing of Damien: Damien Tomaso is framed for storing several kilograms of narcotics in his apartment following an undercover operation, leading to his arrest by Gassman's compromised units.
- The Microchip Revelation: A teenager in District 13 inadvertently films the DISS agents killing the officers and planting evidence, passing the memory card to Leïto before being pursued.
- The Breakout & Alliance: Leïto breaks Damien out of a high-security police precinct. Returning to District 13, they convince the five rival faction leaders (Tao, Molko, Karl, Ali-K, and Little Montana) to cease internal fighting and unite.
- Assault on the Élysée Palace: The united coalition storms the presidential palace, overpowering DISS tactical squads.
- The Climax & Rebirth: Damien and Leïto corner Gassman and expose his lucrative redevelopment pact with Harriburton before the President. Although the satellite-targeted missile launch cannot be aborted, Leïto persuades the President to proceed with precision strikes against the empty, decrepit housing towers, paving the way for complete reconstruction with modern infrastructure, civil rights, and schools.
