Everyone has secrets – the things they don’t want anyone to know…

Aisling Hunter is ordinary. Not beautiful, not special – just another girl in the crowd wishing she was anyone else, anywhere else. Geri West is the opposite – glamorous, confident and popular. Oh, and she’s a malicious bitch. So when the two strike up a friendship it’s a mystery to everyone.

Blackmail, it seems, can be very bonding, and if Aisling keeps Geri’s secret, she wants something in return. Geri might just have the key to Aisling’s own mystery – the whereabouts of her missing mum.

But just as it looks like she might be close to the truth, Aisling is run over in a bizarre car crash. The car is stolen, contains a mysterious stranger and is on an unlit road. Was the crash deliberate or an accident?

The Things I Haven’t Told You is a mystery by 26-year-old writer Lisa McGee, directed by Marcal Fores (26) and set in a school where every student has a dark secret. It stars newcomer Elizabeth Day as Aisling, Nathalie Lunghi (Layer Cake) as Geri and Andrew Lincoln (Teachers) as DC Rae.

The show airs on BBC Three Monday 17th March, 9PM
