Dark Waters

The forbidding regions of the Louisiana bayous drip with cold suspense and moody intrigue as Merle Oberon slips into Dark Waters, the 1944 psychological thriller.
A fake aunt and uncle attempt to drive a nervous young heiress to suicide in order to collect her estate. Aided by the oppressive vegetation, the stifling heat, and the deceptive silence of the swamps, the would-be killers methodically implement a series of terrifying ploys to suffocate the young girl in her own madness.
