Artist Corinne pulls up to the National Gallery in London and sees a monument that was destroyed in a terrorist attack. It fills her with fear, mostly at the fact no one has replaced it in the decade since it was blown up. Her partner Robert accompanies her, but she feels distant from him. The exhibit she's attending is a retrospective on her career, something she finds confusing given the fact she's currently alive. She paints portraits mostly, and of famous people including the King of England. Towards the end of the exhibit, the Prime Minister sneaks in to see Corinne and her paintings. His portrait was painted about a decade ago when he was still just a politician. During this time, he tried to pursue Corinne and even talked her into having sex with him, however she never returned his calls afterwards. Robert, who she's been with for 18 years, doesn't seem to know about Corinne's affair with the Prime Minister. Corinne notes that he has had his own affairs that she let slide. Corinne doubts her abilities and questions her fame later that night. Robert, who is also her agent, supports her when she says she wants to branch out in her abilities rather than repeating the same realist portraits over and over. Graham makes a comment about how rich people are immortal now because of some medical operation or treatment that they're keeping to themselves, and Corinne thinks about how the Queen and Prime Minister looked the exact same as the portraits she drew of them years ago. During dinner at the Prime Minister's later, Minister Graham pushes her to ask if she thinks he's changed in the past decade. He openly admits that he has had longevity surgery, possibly giving him immortality. He offers her the chance to join the elite and become immortal. She pushes to have Robert receive the same treatment, but Graham refuses. He tells her only renowned artists and great minds are allowed the operation and Robert doesn't count. Corinne cannot imagine living without Robert and watching him age as she never changes. That night she tells Robert that she will paint him as her final portrait, even though he has refused for many years. She paints him in her studio over the next five days, and when she finishes with all but a few minor details, she sends him home and finishes alone. Leaving the painting at the studio, she walks home to change for their celebratory dinner. When she returns earlier than their agreed time, she sees that Robert has taken a younger woman up to their apartment. She goes back to the studio, angered and heartbroken by Robert's perceived infidelity. She then goes to the phone to make a call. Fifteen days later, she reappears. Robert is furious and relieved that Corinne has returned and is okay. He mentions that he and someone else had come to look for her, and she asks who. It was his niece, who had just gotten into town that night and called him up to see them. She's about to start art school and Robert wanted to surprise Corinne with her visit, but she disappeared for weeks. A decade passes, and Robert has noticeably aged but not Corinne. He hasn't quite picked up what's happened but he knows she's changed since she disappeared that one night. He tells Corinne that she seems to have lost interest in painting and everything else in her life. As he tells her this, he takes a closer look at her and realizes she hasn't changed physically and he immediately understands what happened. He leaves that night, never to be seen by her again. Decades later, Corinne is handed a letter on the beach by her new beau. It's from Robert's niece, telling her that Robert died. Corinne rips up the letter, notices her new beau is getting older, and scans the beach for new young men.
