Fearless stars Helen McCrory (Harry Potter, Peaky Blinders) as Emma Banville, a human rights lawyer known for defending lost causes and unsolvable cases.

The six-part series is created by Homeland and 24 writer Patrick Harbinson and is produced by Mammoth Screen.

Set in London, the story follows the case of a young girl who was murdered in 2003. Banville is defending a man she believes is wrongly accused of her murder, who insists that he didn't commit the crime. 

With her reputation and career at risk, she digs deeper and begins to discover powerful forces at play within the police and intelligence services who want to stop her uncovering the truth.

The series will also star Michael Gambon (Fortitude, Harry Potter), Wunmi Mosaku (Black Mirror), Jonathan Forbes (Catastrophe) and Robin Weigert (American Horror Story).

Fearless begins on ITV this June.
