In 1943, in the French Alps, Sébastien is a seven year old orphan living with César, an adoptive "grandfather" and his niece, Angélina.

The family lives in the village of Saint-Martin, whose inhabitants, despite the German occupation, secretly organize the passage of Jewish exiles into Switzerland.

Meanwhile, a German patrol, commanded by Lieutenant Peter Braun, arrives in Saint-Martin to put an end to the secret escape route of the Jews.

Knowing that Sébastien will try to prevent Belle from being shot, César gives him the wrong directions to the hunting area.

He lies down on a nearby sled, and starts pawing his way to town when Belle picks up the rope, and begins to tow him.

Lt. Braun, when dug out of the snow, warns her to take another route to reach the border because his soldiers are patrolling the mountain.

The facts narrated in the film are taken from the stories of French writer Cécile Aubry, who were then transported to the small screen as the 1960s television series of the 1960s.

When I was contacted by the production, suddenly everything I had tried watching Belle and Sébastien had awakened and felt compelled to make this film the best".
