The Split

A leading divorce lawyer finds business is personal when she leaves the family firm for a rival and finally faces her estranged father, who walked out 30 years ago.

Things become increasingly complicated for Hannah as she faces Christie's ex-wife in a tricky prenup, and the three sisters meet their father for the first time.

Hannah represents a woman fighting to save the embryos created during a marriage that is now ending in divorce. Oscar's return continues to have an impact on the entire family.

Working on a case involving a member of Parliament, Hannah grows increasingly close to Christie and further away from Nathan and her family. Davey is confronted by Goldie during an important meeting, revealing she is threatening far more than just him if she keeps digging into the finances. As Rose and James's wedding draws near, Ruth hosts a dinner party for all the family, including James's parents, with disastrous consequences - forcing Nathan to make a devastating confession.

Hannah, for so long adept at navigating other people's lives and relationships, is confronted with painful questions about her own. Elsewhere a repentant Nina tries to make up for all the pain she has caused as Rose desperately tries to deal with the aftermath of her sister's outburst. At Defoe's, Ruth is facing some uncomfortable questions of her own as Goldie rejects their financial offer, smelling blood in her legal fight with Davey. At Noble & Hale, Christie finally reaches the end of his patience with Hannah.

Maya, Oscar's second wife, finally arrives in London. As the family try to heal past divisions and celebrate the future, Hannah and Nathan are fighting to save their marriage. Elsewhere Goldie finally has her day in court, only to discover a devastating final secret that changes everything.
