Following this raid, they are taken to the Vélodrome d'Hiver, where Joseph and Noé, his best friend's little brother, meet a nurse, Annette Monod, who will do her best to help them and the other Jews.

A few days later, the parents and their children are deported to an extermination camp, in Auschwitz, only the little ones have to stay hoping for their return which will not take place.

Roselyne Bosch first decided to make a film of the events surrounding the rafle du Vel' d'Hiv because she felt sympathy with the victims.

She began extensively researching the events surrounding the round up and discovered survivor Joseph Weismann and Annette Monod whose memories would eventually form the base of the script.

Bosch decided to portray only real life characters in the film and cast Gad Elmaleh in the role of Joseph's father, Schmuel Weismann.

Actress Mélanie Laurent was cast in the role of the Red Cross worker Annette Monod, whose actions were noble and undisputed, before, during, and after the round up.

Other media are less enthusiastic, such as: In an interview for the French magazine Les années laser in September 2010, Roselyne Bosch compared people who do not cry at the film to "spoiled children", or cynics who "consider human emotions as an abomination or a weakness", just "like Hitler did".

Her remarks were strongly criticized by several French media,[8][9] and by the cinema website Selenie who accused her of "saying one of the silliest thing[s] of the last few years".

Roselyne Bosch sued the website for publicly insulting her, but her case was dismissed in April 2013, the Paris Court judging that the critic did not exceed the boundaries of freedom of expression.
