In 1960, moments before filming the final episode of The Lucy-Desi Comedy Hour, Lucille Ball and Desi Arnaz send scathing messages to each other through a pageboy.

Co-stars Vivian Vance and William Frawley comment on the tense situation, but everyone puts on their best front as Desi introduces them for the final time and Lucy emerges to a warm welcome from the studio audience.

Shortly after, Lucy's grandfather is sued by the family of a neighborhood boy who was accidentally shot and paralyzed by someone target shooting under his supervision.

After being released from MGM, Lucy meets silent movie legend Buster Keaton, who is convinced of her talent as a clown and takes her under his wing.

In the present day, moments after the filming ends, Lucy and Desi hold hands as they leave the studio, content with remaining friends and proud of what they have accomplished.
