This darkly atmospheric shock-thriller takes you on a white-knuckle ride inside a cell of homegrown extremists dedicated to bringing jihad to the streets of Paris. Sam is a Franco-Algerian journalist hoping to write a tell-all exposing the threat of domestic terrorism. Using his knowledge of Islam, he infiltrates a small cadre of extremists led by Hassan, a disgruntled shoe salesman whose chief leadership credential is having met “the principals” on his pilgrimage to Mecca. Hassan instructs everyone to “become invisible.” From the outside, it all appears frighteningly ordinary, except for Sam, who is now in the precarious position of a normal guy trying to look like an extremist trying to look normal. Sam discovers that the cell is comprised of young men who, far from marching in lockstep, have wildly different motivations. But as the plan moves closer to fruition, suspicion grips the conspirators, putting more than his book in immediate danger.
