In a seedy Hollywood motel, a down-and-out ventriloquist overdoses in front of her son and daughter, scarring them for life. Eighteen years later, the son, who has not spoken a word since his mother's suicide, and daughter, depart on a road trip to Las Vegas. Still haunted by their childhood memories, they are unable to fulfill their mother's dying wishes to uphold the family bloodline and become great ventriloquists. Entranced by the dummy's commands, the long journey plunges them further and further into darkness as they begin a murderous rampage across the desert.
