In this thriller, Karim Hamida (Richard Berry), an undercover agent for an Arab government, and Simon Atlan (Patrick Bruel), a Jewish cop, join forces to fight terrorism. To begin with they are paired by their superiors to bust up an international heroin ring operating in French high schools. At first, they haven't got anything good to say to each other, but when they catch wind of a terrorist hiding out at an embassy, they join forces. This same terrorist is posing as the director of an "Islamic cultural center" which is actually a school for mayhem. These two men infiltrate the center and disrupt its operations, nearly losing their lives in the process. The bad guy swears vengance, and begins a campaign of terrorism aimed specifically at these two men.
