Produced by Indian Summers and The Missing outfit New Pictures, the series is penned by Australian writer Kris Mrksa, who has written episdoes for Australian series including The Slap, Underbelly and Glitch.

Requiem tells the story of a young woman, who, in the wake of her mother’s death, sets out to learn the truth about herself, even to the point of unravelling her own identity.

The series logline is: What if your parent died and you suddenly discovered that everything they’d said about themselves, and about you, was untrue?

Requiem will be executive-produced by Willow Grylls, Elaine Pyke and Charlie Pattinson for New Pictures and Polly Hill for BBC One.

If Netflix does sign on for Requiem it is expected to take streaming rights in a number of markets.

New Pictures is also behind six-part BBC One series Rellik.
