Believing that the world will end that very day, three mental patients Coco, Tsumuji, and Satoru set out upon a journey. Walking upon the tops of the walls of the city, they seek to find a picnic spot with the best vantage point to view the final event.
Unfortunately the movie Picnic is not yet available on HBO Max.
