In 1979 or so, I saw what I remember as being a short story on television titled "Bobby" (If memory serves). The tale was about a married couple who had a son named Bobby that fell off of an overpass or a cliff to his death and pulled into the ocean never to be found.
His grief stricken mother cleared out the living room and drew a large pentagram on the floor and read incantations to try to bring her dead son back to her. Bobby soon returned home shortly and told her he was found by a family who took care of him until his return home to his mother.
She then asked him if he had eaten and that she would make him some lunch and while eating he told his mother that he wanted to play hide and seek. She declined because she wanted to visit with him and he became angered and flipped the table over and ran off into the house to begin the game.

I have been scouring the net for years trying to find this film but have had no such luck.If you know where I may find this film I would be ecstatic. Please respond if you need more info or have any suggestions.
Thanks
