The Split is an authentic, layered and witty exploration of modern marriage and the legacy of divorce through the lens of the Defoes - a family of female lawyers at the heart of London's fast-paced and emotionally-charged divorce circuit.
Esteemed divorce lawyer Hannah (Nicola Walker) quits the family firm when her mother Ruth (Deborah Findlay), formidable personally and professionally, refuses her promotion. Landing at a rival firm alongside old flame Christie (Barry Atsma), Hannah navigates scandalous affairs, big-figure settlements and fraught relationship battles - coming head to head with Ruth and impulsive sister Nina (Annabel Scholey) in the bitter divorce of Goldie (Meera Syal) and multi-millionaire husband Davey (Stephen Tompkinson). Meanwhile, the marriage of younger sister Rose (Fiona Button) looms on the horizon.
When their estranged father returns after 30 years the sisters are forced to confront their past. Facing the reality of her dad's abandonment, and reconnecting with ‘the one who got away' Christie, Hannah begins to question her relationships with the men in her life - including her seemingly contented marriage to the smart and affable Nathan (Stephen Mangan).
