Another character in the film is Messaoud.
He falls in love with a French woman.
He writes many letters to her.
But the army officers change these letters.
They read them first.
Then they remove any writing they do not think the woman should see.
Messaoud does not know that the officers are interfering in this way.
Abdelkader is the third character.
He is a very good soldier.
But he never has the chance to become an officer.
He believes this is because he is not a "White" French man.
He becomes very angry and leaves the army.
Then there is the character of Yassir.
He, too, has decided to fight in the French army.
But he also feels that the army officers are unfair.
They treat the colonial soldiers differently from the white soldiers.
But he decides to stay and fight.
And he shows great courage in battle.
The director of the film was Rashid Bouchareb.
Mr. Bouchareb is French.
But his family is from North Africa.
He says that the colonial soldiers fought very hard for France in the Second World war.
And he believes that France owes them for this!
But France has simply forgotten about them. He said,
"It is my aim to open a forgotten chapter in the history of France."
So why were these soldiers so important?
What part did they play in the Second World War?
In 1940, German forces invaded the north of France.
The Germans took only six weeks to capture the capital city, Paris.
But the Germans were not going to stop there.
They planned to capture the rest of the country too.
The French Prime Minister was worried.
The French government had been in Paris.
