The Letter (1940)

A woman living on a remote rubber plantation shoots a man and claims it was self-defense. Her story is accepted by nearly everyone, and her acquittal seems inevitable. But her lawyer harbors doubts, and when a letter surfaces, written in her own hand, it threatens to unravel her carefully constructed story. As the truth teeters on the edge of exposure, her façade of innocence begins to crack, revealing a more dangerous woman.
