Burgeoning writer Arabella returns to London where she's greeted by a deluge of messages from her literary agents. With a matter of hours left to finish a draft of her second book, she plans to pull an all-nighter - but is soon tempted to join a friend on a night out.

Lunch with Terry gets Arabella thinking about the hazy events of the previous night, prompting her to probe Simon for answers. Increasingly desperate to put together the pieces, Arabella drops by Simon's apartment and, later, finds herself at an unwelcoming doorstep.

Three months earlier, Terry visits Arabella in Ostia, Italy, where she's living large on her agents' dime. After procuring party favours, Arabella and Terry each have a wild night of their own.

Back in London and two months after the incident, Arabella meets with a therapist who encourages her to find ways to cope with her trauma. Still anticipating the first draft of Arabella's book, her agents assign another client to help her with the writing process.

Arabella attends a support group for rape and sexual assault survivors run by a high school acquaintance, Theo. In a flashback, teenage Arabella and Terry intervene when a resourceful, troubled young Theo tries to flip the narrative on consensual sex gone sideways.
