SundanceTV and BBC One have released first-look images of Abi Morgan’s divorce drama The Split, produced by Jane Featherstone’s Sister Pictures.

The six-part drama stars Stephen Mangan (Episodes) and Nicola Walker (River, Last Tango in Halifax) alongside Anthony Head (Buffy the Vampire Slayer), Meera Syal (Goodness Gracious Me), Fiona Button (Lip Service), Deborah Findlay (Leaving), Annabel Scholey (Being Human) and Barry Atsma (Hector and the Search for Happiness).

It explores 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. Produced by Lucy Dyke (Black Mirror, Ripper Street) and directed by Jessica Hobbs (Broadchurch), the show shot on location in London.

Walker plays esteemed divorce lawyer Hannah, who quits the family firm when her mother Ruth (Findlay), formidable personally and professionally, refuses her promotion. Landing at a rival firm alongside old flame Christie (Atsma), Hannah navigates scandalous affairs, big-figure settlements and fraught relationship battles – coming head-to-head with Ruth and impulsive sister Nina (Scholey) in the bitter divorce of Goldie (Syal) and multi-millionaire husband Davey (Stephen Tompkinson). Meanwhile, the marriage of younger sister Rose (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 (Mangan).

The drama is one the first new original production from Featherstone’s indie Sister Pictures, which is also producing Hulu and Channel 4 30-minute comedy drama The Bisexual, HBO and Sky thriller Chernobyl, and Netflix and BBC One Tokyo-set detective drama Giri/Haji.

BBC Worldwide is handling international distribution.
