The Other One starts on Friday 5 June at 9pm on BBC One and will be available as a boxset on BBC iPlayer.
The Other One is a comedy about what happens when you discover your dead dad has a secret family, and you now have a brand new sister.

This is a love story to siblings, mothers and crap dads. Throughout the series our four leading women try to make sense of their newly found sisters and sort-of-step-mums.

The Other One stars Siobhan Finneran (Downton Abbey, Happy Valley), Rebecca Front (The Thick of It, War and Peace), Ellie White (Inside No 9, The Windsors), Lauren Socha (Misfits, Catastrophe) and Amit Shah (Hospital People, Stag, W1A).

Created and written by Holly Walsh (Motherland, Dead Boss) and Pippa Brown (Psychobitches, Bad Education).

It is a Tiger Aspect production for BBC One.
