Alfred Hitchcock, 1959

While staying at an Alpine ski resort, English mountain climber Mark learns that a fellow Englishman, a young climber, has perished on a nearby mountain, his body awaiting retrieval. Mark breaks the news to the dead man’s pretty young widow, Stella, before setting off to recover the corpse. The attempt to fetch the body is botched, the corpse falling from the mountain deep into a crevasse below, making it irrecoverable.
