This gripping and wrenching thriller tells the story of Ilan Halimi who was kidnapped for ransom in a Paris suburb. His captors, who dub themselves The Gang of Barbarians, operate under the assumption that his Jewish heritage means he is worth a lot of money. Taking the audience through the harrowing experience of the Halimi family and sharing a searing insight into Ilan's vicious ordeal, the story tracks the massive but futile investigation doomed by near-misses and tragedy that triggered a national outcry. For 24 days the police, insistent upon handling the case as a normal for-ransom kidnapping, failed to recognize the anti-Semitic overtones of the abduction. Faithfully reenacting events from the view of the various characters, Tout, tout de suite raises troubling questions about the state of anti-Semitism and race relations in contemporary France.

Cesar is a young schoolboy living in Paris with his family. Their life is ordinary, but Cesar wants more excitement (which he creates, in one instance, by claiming to his teachers that his father has been arrested). During the school holidays, Cesar and his friend Sarah decide to help their mutual friend, Morgan, find his father who supposedly lives in London. Each one tells their parents that they're staying with the other two, and together they sneak out to begin their search.
