The Red Needle (1951)

A young woman, Maya, is treated in a mountain hotel, where her husband joins her every Saturday. She falls in love with an attractive lawyer, who has come to this hotel in Savoie to successfully climb the Aiguille Rouge. The lawyer rejects Maya at first, but ends up becoming her lover and promises to run away with her... once the Aiguille Rouge has been climbed. But a storm breaks out during the ascent, and the lawyer dies, struck down.
