When a work trip to New York extends into a lonely solo holiday, Maggie unexpectedly finds herself entering into a whirlwind romance.

Maggie decides to ‘grow-up’ by focusing on work and swearing off sex and booze. Driving everyone mad with her new ‘grown-up’ behaviour, events come to a head at the Heirs & Graces.

Maggie and Birdy seek to rekindle their closeness with makeovers, baking cookies and trips down memory lane, only for tensions to finally explode in a big way.

The girls settle into their new lives in London. Birdy continues to date Nathan. As things between them start to get serious, Maggie realises that Birdy is starting to slip away.

Struggling to come to terms with Birdy’s blossoming relationship, Maggie heads to her hometown for a messy and humiliating weekend that leads her to reevaluate her relationships.

The girls throw a queen-themed house party. It’s clear Birdy would rather be with Nathan and despite Maggie’s protestations she finally bails, leaving them to party without her.

Childhood friends Maggie and Birdy move into their first London house-share, along with Nell and Amara. When Maggie meets hot musician Street, events take an unexpected turn.
