After visiting her long-distance boyfriend in Italy, burgeoning writer Arabella returns to London, where her literary agents have left her several frantic messages; with mere hours left to finish, she is tempted to join a friend on a night out.
Arabella thinks about the hazy events of the previous night while having lunch with Terry, prompting her to probe Simon for answers; Arabella drops by Simon's apartment, only to find herself at an unwelcoming doorstep.
Terry visits Arabella in Ostia, Italy, where she's living large on her agents' money; after procuring party favors, Arabella and Terry each have a wild night of their own.
Two months after the incident, Arabella meets with a therapist who encourages her to find new ways to cope with her trauma; Arabella's book agents assign another client, Zain, to help her with the writing process.
The day finds Arabella reassessing a sexual encounter with Zain and, following a promising new lead in the investigation, opening up to Biagio about her assault.
Much to Terry's disapproval, Arabella attends a support group for rape and sexual assault survivors run by their high school acquaintance Theo; in a flashback to 2004, teenage Arabella and Terry intervene with a young Theo.
Reeling from a demoralizing development in the investigation, Arabella hatches a risky plan and convinces an adverse Terry to bankroll it; still navigating his own assault, Kwame challenges himself to explore the full spectrum of his sexuality.
Arabella's bloated social media presence finds her more glued to her phone than ever, perpetually internalizing the stress of her followers; at Terry's Halloween paint and wine, Kwame opens up to the girls about his recent sexual experiment.
After Simon mistakenly drops a bomb on Arabella, she heads to her mom's birthday dinner, where painful, long-forgotten memories bubble to the surface; Kwame's no-strings-attached hookup bender leads him to Tyrone.
Arabella's obsession with Della leads to unexpected progress on her book; Kwame wades into uncharted waters with Tyrone and attempts to make amends with a disgruntled ex-flame.
When Arabella's memory of January 22 comes flooding back to her, she drags the last of her demons out, once and for all.
