A homicide detective teams up with a criminal profiler to catch a serial killer whose crimes are inspired by the children's game, Hangman.

The rumored daughter of Sarah Good, the first witch to be tried and hung during the Salem Witch trials, lives and commands the spirit world at her fingertips. Irene, as she is known, must sacrifice the lives of a small group of youths every 30 years for preserving her own youthful appearance, powers and prosperity. On this day, Irene sets the bait for Dalton, an unassuming young man looking for closure in his brother's accidental death. She promises Dalton the allure of reconnecting with his deceased sibling while suggesting he bring his friends along for the show. Sam, Dalton's closest friend, ignores the warning signs, tags along for the ride and finds herself the only person left alive after a night of gruesome events.
