After visiting her aspirational long-distance boyfriend in Italy, writer Arabella returns to London, where she is greeted by a deluge of frantic 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. Growing increasingly desperate to put together the pieces, Arabella drops by Simon's apartment – and, later, finds herself at an unwelcoming doorstep. Meanwhile, Terry has a lousy audition, and a concerned Kwame rushes to Arabella's side.

Strapped for cash and still unable to produce a draft of her book, Arabella takes a job working alongside Theo at a vegan delivery start-up. Birthday girl Terry takes covert measures to ensure Simon won't make a surprise appearance at her party. The festivities find Kwame avoiding reminders of his assault while Terry airs her suspicions about Theo.

After Simon inadvertently 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, a stranger in search of a different kind of connection.
