In 1928, spirited teenager Beatrix Jenkins visits the Spectral Valley Museum during a school field trip. Drawn to a mysterious pearl ring in a restricted exhibit, she sneaks into a closed-off section to examine it. Before she can return the ring, she is spotted by a security guard. To avoid punishment, she tries to distract him and flees the museum. Tragically, she is struck by a car and killed instantly. Unbeknownst to her, the ring is cursed, and her spirit becomes bound to it, leaving her to haunt her family home for nearly a century.
In the present day, 17-year-old Cole Sanchez moves into Bea’s former house with his mother after his father’s death. While exploring his new room, Cole finds the pearl ring. Upon wearing it, he begins experiencing supernatural events and eventually meets Bea’s ghost.
