A middle-aged man on a bench in a London park sees Paul McCartney sitting nearby. Resolving to approach him, he puts gathers his thoughts and takes up the thread of his memories, marked by the Beatles’ repertoire . . . A mother plays ‘Yellow Submarine’ on the harmonica to her seven-year-old son. She dies and leaves a void. A few months later, the Beatles split up. Another great loss in his life. A distant father, silent and abusive doesn’t help. Only when the boy finds shelter in this own yellow submarine – a room in the basement of the public library – does his life begin to take shape.
