Kuwahata Chokichi used to be a famous actor, but now he's suspected to be suffering from dementia. He is betrayed by his older daughter, Yukiko, her husband-cum-his-former-disciple, Ikuo, and Yukiko's lover, a mysterious driver, and gets sent to a high-class old folks' home. One day, Choukichi runs away from the home and wanders to the beach where he meets his younger daughter, Nobuko, who he had with his lover. Although he had thrown Nobuko out in the past, he begins to imagine seeing her as the image of Cordelia, who is the beloved daughter of King Lear, after talking to her. Gradually, his past memories start to come back to him, and Choukichi heads towards the world of insanity.
Unfortunately the movie Lear on the Shore is not yet available on HBO Max.
