The episode begins with Noah and Anton heading to Montauk to visit Irene, a woman who once worked with Alison at the Lobster Roll and knows a lot about her past. Meanwhile, Alison is trying to get her life back on track by focusing on her daughter, Joanie, who has recently returned from Paris to live with her. She hires a new employee for her snack bar and tries to make amends with Cole, who is still hurt by their breakup.

At Irene's house, Noah and Anton meet her daughter, who is a writer and has just published a book about her father, who died in the same accident as Alison and Cole's son, Gabriel. She reveals that her mother had an affair with Cole's father, and that her father was actually in love with Alison, not Irene. This news shocks Noah and Anton, who had no idea about any of this. They also learn that Irene is in a nursing home and suffering from dementia, and that Alison used to visit her often.

Back in Montauk, Alison has a run-in with Cole's new girlfriend, who is pregnant with his baby. She tries to be civil, but it's clear that there is still tension between them. She also has a conversation with her therapist, who suggests that she write a letter to herself about her hopes and dreams for the future. Alison takes this advice and starts writing, but the exercise proves to be more difficult than she thought.

Noah and Anton return to Los Angeles, where they attend a party at Janelle's house. Anton is excited to see his mother, but their reunion is cut short by an argument over his future plans. Noah runs into a former student of his, who is now a successful actor, and they catch up. The actor invites Noah to a party the next day, but Noah declines, saying he has to work.

At the party, Anton reconnects with another former student of Noah's, who is now a struggling writer. They have a conversation about the creative process and Anton's future, and Anton realizes that he wants to be a writer too. Meanwhile, Noah has a conversation with Janelle, who is still angry about the way he treated her during their relationship. Noah tries to apologize, but Janelle isn't interested in forgiving him.

After the party, Noah goes to a bar and meets a woman named Sasha, who is a professor at a nearby university. They have a conversation about literature and politics and Noah feels a connection with her. They end up spending the night together, but when he wakes up in the morning, he realizes that he has left his phone at Janelle's house.
