District 13: Ultimatum
2009 film by Patrick Alessandrin

District 13: Ultimatum, also known as D13-U (French: Banlieue 13 – Ultimatum or B13-U), is a 2009 French action thriller film and a sequel to the 2004 film District 13. Directed by Patrick Alessandrin and written and produced by Luc Besson (who also wrote and produced the first film), the film sees parkour artists Cyril Raffaelli and David Belle reprising their original roles of Damien and Leïto.
Plot
Three years after the events of the original film, the authorities are attempting to return law and order to ravaged District 13. However, their efforts so far have failed to do so. The death of gang overlord Taha Ben Mahmoud has left a power vacuum, and total control of the area is now being fought over by five rival territorial gang lords who want to step into Taha's position. Leïto tries demolishing the walls surrounding the district on a daily basis, but is told to stop by African gang lord Molko, who sees the walls as protection from outside the district.
After single-handedly eliminating a major drug dealer, Damien is framed for drug dealing and arrested, but manages to make a brief call to Leïto to come rescue him.
Meanwhile, corrupt government agents from the Department of Internal State Security (DISS), led by Walter Gassman are bent on destroying the five tower blocks at the heart of District 13 with tactical precision bombing, and building luxury flats after the area is cleared. In order to spark conflict with the district's gangs, the DISS shoot two policemen, dump their car in District 13, and prompt several gang members into gunning down the vehicle, making it look like the gang members killed the policemen. The footage of the incident convinces the French President to carry out the strike.

Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Apr 14, 2026. The linked authority identifier is Q1144055. VIAF identifies the subject as 185260108. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
