The first hour of the film follows a group of young revolutionaries as they orchestrate an elaborate plan that involves the planting of bombs across the city of
Paris. It is revealed via flashback that the bombs are made of a substance called
semtex, which has been provided to the young terrorists (all either teens or university students) by Greg, the only independent adult in the group. Their plan involves the planting of bombs in cars, high-rises, and government buildings, assassinating the head of HSBC France, and setting fire to the
Jeanne d'Arc. Sarah, her boyfriend David, and Yacine each infiltrates the floor of a skyscraper to plant a bomb, aided by Fred, an accomplice who works as a security guard at the target buildings. Whilst searching David's floor, Fred finds and shoots to death an innocent office worker who was attending a call. This alerts another security guard, who kills Fred despite his appeals. David hears this from a neighboring hallway and runs, throwing away his bomb without having set it. After detonating the bombs remotely, the young terrorists all convene to a department store situated in the heart of Paris, intending to stay there until evening of the next day so as to escape the attention of the authorities. The rest of the group consists of André, Samir, his sister Sabrina, and Mika, the youngest in the group. They hide while the security team searches through it looking for stragglers. One of their number, Omar, turns out to be another accomplice to the terrorists. He tells the group that he has bound and gagged the rest of the security team and shut down all the security cameras (it is revealed later that he shot and killed the guards). To their dismay, the group realizes that two of their number are missing: Fred and Greg. David informs them of Fred's death, but the fate of Greg, whose task was to assassinate the bank executive, remains a mystery. The group spends the night at the store, eating food from the grocery store and stealing clothes from boutiques. Omar turns some TVs on display on, allowing the group an insight into the state of the world outside. A panic has spread as the authorities search for the bombers, and this knowledge satisfies the group. They remain agitated, however, worrying about whether Greg has been captured and been coerced into revealing their whereabouts. David leaves the store to smoke. He encounters a homeless man whom he feels sorry for and invites into the mall for food, telling him his father owns the store and has allowed him and some friends run of the place. The man declines, saying he is waiting for his wife, but David insists upon leaving the door wedged open, in case the couple should want to enter. In another excursion outside, he meets a cyclist, who he asks for information about the state of affairs in the city. She informs him that the authorities are still searching for the perpetrators of the bombings, which she believes "were bound to happen," echoing the inevitability of something André said to Sarah earlier in the film: "Civilization is a condition for the downfall of civilization." When David returns, he finds his fellow renegades even more on-edge, now partaking in impromptu performances and applying makeup onto each other and themselves. Mika has a dream of Greg walking up to him and telling him he forgot to hide his gun, which exposed him. Greg tells him he committed suicide on the streets and asks him if he would have done the same before disappearing, leaving a mannequin in his place, which severely unnerves Mika. Sarah screams when she sees the homeless man and his wife walking up the escalators, having taken David up on his offer. David consoles the group, telling them they have nothing to fear, and they begrudgingly concede to allowing the homeless couple access to the store. David and Sarah have sex, after which he turns a TV on to learn that the authorities are aware that the terrorists are holed up in the store, and are gearing up for action. He informs André of this development in a panic, and is told to hold-off from telling the others. He returns to Sarah, who is fast asleep. Yacine, lounging in a bathtub, tells Samir about the
use of children as minefield testers during the
Iran-Iraq War, specifically that the children were promised "heaven" after their death. André sets up the remainder of the semtex against some pillars, planning on using at as leverage when the authorities arrive. David eventually informs the rest of the group of the incoming forces and they all hide across the shop once again in anticipation, deathly afraid. A squad of heavily armed police storms the store, and the youngsters attempt to surrender, holding up their arms and appearing passive. The police remorselessly shoot every single person regardless, including the homeless couple. In quick succession, all the young members of the team are gunned down, with their attempts to bargain or plea failing without exception, leaving a string of bodies embellishing the floors of the dark store. Samir, thinking of Yacine's story about the minefield testers, says the word "Heaven" to himself and trades gunfire with the police before they corner him behind a couch. He pleads for help, and the film ends with the sound of a gunshot, followed by an immediate cut to a screen-filling shot of raging flames. ==Cast==
