S1E9: Ring a Ring of Roses

Laurie Thornton and her fiancé, George, set out to visit her former college roommate, Helena, at her family's remote estate, but their journey is interrupted by an eerie roadside vision of a violent clash between a father and daughter. They soon discover the haunting is tied to a cursed family heirloom: a ring with a rose-colored stone, rumored to prevent its female bearers from marrying. Later, Helena’s mother insists Laurie accept the ring as an engagement gift — which she does, but soon regrets.
