While trying to get their lives back on track after the loss of their four-year-old son, Bryn and Paul Shaw move to the charming old Beacon Apartments. Bryn begins seeing a ghostly little boy skulking around the building. With the help of an eccentric young professor and a tough old beat cop, Bryn tries to uncover the details of the boy's death. She hopes that freeing the child will allow him to carry a message to her son. Too late she realizes a second malevolent entity stalks the halls of the Beacon: one that doesn't want the boy to escape.
