BBC Three now has a new home online. To mark the move, it's making a big push with its own original programming. And now we have the first trailer for what looks like being a harrowing drama called 'Thirteen'.
It tells the story of a woman called Ivy (played by Jodie Comer, who was the other woman in last summer's drama hit 'Doctor Foster'), who makes a surprise return to her family 13 years after being kidnapped and kept in a cellar.
Is she who she says she is? And if so, what happened while she was imprisoned? You can be sure the five-parter will be full of twists and turns.
The show also stars Aneurin Barnard as Tim Hobson, Ivy's boyfriend (you might recognise him from BBC One's 'War and Peace'). Plus Richard Rankin ('From Darkness'), Valene Kane ('The Fall') and Natasha Little ('Wolf Hall').
There's no exact airing date yet, but it's expected to be available around the end of February.
It will be available on the Daily Drop page, which hosts all the new BBC Three content. It will also air on either BBC One or BBC Two at a later date, as will all long-form BBC Three content.
