It's 2010 and the government has erected concrete barriers around the hard-to-handle suburbs near Paris. As a public service, local lad Leito is busy destroying 20 kilos of heroin in the bathtub of his tower-block apartment when reps of local kingpin Taha come looking for him. Leito escapes, however in retaliation, Taha sends his baddies to kidnap Leito's sister, Lola. Soon, Lola is strung out on heroin and Leito finds himself doing sit-ups in prison. Meanwhile, undercover cop Damien captures a Latino crime boss and shuts down his illicit casino, against very stacked odds. As a reward, Damien is assigned to penetrate notorious Suburb 13 and stop the countdown on a deadly bomb that was hijacked by Taha.
