Its 2013 and the inhabitants of the Parisian ghetto District 13 have been walled in and left to rot as the area has become so dangerous. When a ghetto gang-member steals a neutron weapon it falls to super-cop Damien (Cyril Raffaelli) and Leito (David Belle), a ghetto-dweller wrongly imprisoned, to stop him. They are both hard men and experts in Le Parkour, an extreme sport involving roof-running, building-to-building leaping and wall scaling.
