Anna Friel returns to ITV in their new Sunday night drama Butterfly.
Written by Tony Marchant, the three-part series centres around 11-year-old Max, played by newcomer Callum Booth-Ford, who from a young age has identified as a girl but in a bid to earn his father's approval, has suppressed these feelings.
His parents, Vicky and Stephen Duffy are played by Anna Friel and Emmett J. Scanlan, are separated and Stephen is unaware that within the confines of the family home, Vicky allows Max to dress and behave as a girl.
With both parents divided, will Max find the courage to identify as a girl and express herself as Maxine? And will her family be able to accept her for who she really is?
