Le Jeune Folle on AllMovie

La Jeune Folle is based on a novel by Catherine Beauchamp. Daniele Delorme delivers a brilliant performance as an Irish colleen named Catherine, who because of her vivid imagination and unorthodox behavior is considered to be a lunatic. In one of her delusional moments, she imagines that her dead brother is calling for her. She searches for her brother within the ranks of the Irish rebel organization responsible for his death, falling in love with the man (Henri Vidal) who, unbeknownst to her, ordered the killing. Upon learning the truth, Catherine lives only for revenge, leading to an explosive, almost operatic climax. La Jeune Folle was released in English-speaking countries as The Mad Girl and Desperate Decision.
