After visiting her boyfriend in Italy, Arabella returns to London and a deluge of frantic messages from her literary agents. She plans to pull an all-nighter to finish a draft of her book but is tempted to join a friend on a night out.

Disturbed by what little she remembers of the previous night, Arabella attempts to retrace her steps, but Simon seems reluctant to help her. Meanwhile, Terry has a lousy audition.

In a flashback, Terry visits Arabella in Ostia, where she is living it large. After procuring party favours from Biagio, Arabella and Terry each have a wild night.

2 months after the incident, Arabella meets with a therapist, Carrie. Her agents assign another client, Zain, to help her with the first draft of her book. Kwame introduces his new love interest, Damon, to a stranger he met online.

Arabella reassesses a sexual encounter with Zain and opens up to Biagio about her assault. She is in danger of breaking the internet when she goes off script at a writing summit. Kwame is prompted to report his assault to the police.

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 when Theo attempts to flip the narrative on consensual sex.

Arabella takes a job working alongside Theo at a vegan delivery start-up. Terry takes covert measures to ensure Simon won't make an appearance at her birthday party.

Reeling from a demoralising development in the investigation, Arabella hatches a risky plan to "spark joy" and persuades Terry to bankroll it. After 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, internalising the stress of her followers. At a Halloween 'paint and wine' party Kwame opens up about his sexual experiment.

After Simon drops a bombshell, Arabella attends her mum's birthday dinner, where painful, long-forgotten memories resurface. Kwame's no-strings hook-up bender leads him to Tyrone, a stranger in search of a different kind of connection.

Arabella re-engages with her work and continues staking out the scene of her attack. Kwame follows Tyrone into uncharted territory, and Terry has some luck in work and romance.

When Arabella's memory of her assault comes rushing back to her, she drags the last of her demons out from under the bed - once and for all.
