Suranne Jones is set to create and star in an emotional family drama for ITV about a woman living a double life.
The Vigil actor will take a lead role in Maryland, which she will also co-create with screenwriter Anne-Marie O’Connor, commissioned by ITV as a three-part series.
It looks at the relationship between sisters Becca (Jones) and Rosaline, brought together by family tragedy and a strange discovery.
Jones said: "Maryland delves into family dynamics and the way in which we ‘label’ each other, sometimes never letting ourselves or our siblings break free from those roles. We look at how we grow apart from one another and how sometimes we don’t really know anything about the people we call our own.
"I love how complex sibling relationships can be and I’m thrilled we get to do it over three wonderful hours and not as a ‘side story’.
"Maryland is an uncomfortable, funny and sometimes difficult story with two sisters at its heart and we can’t wait to take our audience along for the ride."
