The story begins in 1964. James (Armie Hammer) is an art critic. One day, he came to the personal exhibition of the famous artist Giacometti (Geoffrey Rush) in Paris. What James did not expect was that he had the honor to meet Giacometti himself. Not only that, Giacometti also invited him to his studio to be his model. In this way, James began to have close contact with this legendary artist. In the crowded and narrow studio, James witnessed the appointment and pain that extraordinary talent brought to Giacometti. When painting James's portrait, Giacometti repeatedly tore up his completed paintings, and his creation seemed to be in a bottleneck. In the end, can he complete the portrait as scheduled?
