Out of an Old Man's Head (1968)

On the way home to the run-down shack he lives in with a can of dog food meant for himself, Johan Björk is accidentally covered by a pile of car tires thrown by a man who fails to notice him. His cries for help aren't perceived by anyone except one drunk, who is caught by the police when calling for assistance. Finally, at night, a young couple making love on the pile of tires notice him. They help him to get up and assist him to his home. He is hurt in the leg and understands that he can't take care of himself anymore, so he is put in a retirement home. At the home, Johan is sitting in a wheelchair staring out the window, mumbling for himself about his past to an animated flashback.
