Every morning at the same hour on the golf course, Jack Hartington hears mysterious cries for help coming from a cottage. He speaks to the resident and learns that she has unsettling dreams of a woman with a blue Chinese vase. Believing that the cries for help are from the late Mrs. Turner, the former resident of the cottage, Jack hires a psychic investigator to spend a night in the house, a night which proves to have startling results.
