Inspired by a legend from Provençal folklore, the film tells the story of the Tarasque and Saint Martha. The Tarasque, a gigantic dragon, had settled in a pond near the small town of Tarascon, killed everything that lived, devoured animals and people, burned crops. People feared and hated her, but no one dared to confront her. Martha, a young girl, managed to dominate and tame the dragon, which became completely docile and harmless. But despite the young girl's pleas not to hurt her, people wanted to take revenge on the monster.
