BBC One's upcoming comedy series The Other One follows two young women, both called Catherine Walcott - sisters who had no idea of each other's existence until their father's untimely death at a birthday party.


Written by Holly Walsh, the series follows Cathy, a slightly uptight and affluent young woman whose life is completely upended when her father Colin suddenly dies, and she learns that Colin had had a secret second family - and a second daughter, the fun-loving Cat, who also had no idea of Cathy's existence.

The only thing the pair have in common is DNA and their names (a sneaky ploy on Colin's part), but both have always wanted a sister...

The series, which first debuted as a pilot back in 2017 before a hiatus, follows the two half-sisters and their respective mothers as they come to terms with Colin's actions.
