Doctor Hanray, a PhD physicist, is an old man, apparently ill with radiation sickness, who visits his ancestral home in the present, or near past (post WWII and post atomic bomb development and detonation). He has to obtain permission from the guards who have turned his small village into a "reservation" in order to visit his parents' graves. He is greeted with military brusqueness at first until they realize who he is and then treat him with honor as one of the developers of the atomic bomb, an honor that makes him "wince" (his word) internally whenever this fact is mentioned.
While looking around and trying to get his childhood bearings, despite the absence of landmarks with all the new building and destruction of the old, Dr. Hanray spots a young lad - age 14 - coming up the road. It is he as his younger self. The younger Dr. Hanray takes him home where he meets his mother and physician father. He wishes to convince his younger self not to go into science, as his father says is his wish, clearly in order to sway the future development of the atomic bomb. He is met with a cold reception - but civil - by his mother, father and younger self until Doxy, their dog, comes in and recognizes the identity of Dr. Hanray elder with the boy. Doxy's warmth turns the mood around but in the end Dr. Hanray is unsuccessful in dissuading the boy and he leaves only to wake up on the ground outside his deserted home.
