This new documentary by the father-and-son directing team of Daniel and Emmanuel Leconte pays tribute to the 11 journalists of the French satirical magazine Charlie Hebdo who were killed in the January 2015 attack by radical Islamic extremists.

On January 7, 2015, French satirical weekly Charlie Hebdo was the victim of a terrorist attack that killed 12 people, including some of the greatest French cartoonists such as Cabu, Wolinski, Charb, Tignous and Honoré. The following day a policewoman was shot dead in the street. On January 9, another attack targeted the Jewish community. Four hostages were murdered. This film pays tribute to all these victims.
