Vincent finds himself under attack for no apparent reason overnight. When the phenomenon intensifies, he must run and change his way of life completely.

Set in the ghettos of Paris in 2010, an undercover cop and ex-thug try to infiltrate a gang in order to defuse a neutron bomb.

As he waits for the inevitable police assault, this ordinary man looks back over his life and the events that led him to commit such an act.
