I need a title for an old movie.1970's
I movie played on TV in the Cincinnati area in the 1970's. I can remember a scene where the father and son were on a raft, the father went under the water and some kind of radiation type thing came down and the boy got radiation because he was above the water. One of the last scenes in the movie is you hear dogs howling, the father and his date come home to find the son was under the Xmas tree opening gifts but he had died. Can anyone help me with this... I have been looking for over 15 years...
