Apple Tree Yard - Season 1

Dr Yvonne Carmichael seems to have it all - a respected career, a beautiful home and family. However, nothing is ever as it appears, and when she receives an unexpected proposition from an enigmatic stranger, Yvonne is shocked by the passion he awakens in her. But gradually she begins to realise that there is much more to her lover than meets the eye, and she could be playing a very dangerous game indeed.

Devastated by the horrific events of the previous night, Yvonne returns home. Desperately trying to come to terms with what's happened, she unexpectedly finds herself confiding in Costley.

When the situation intensifies, Yvonne becomes ever more terrified and once again turns again to Costley. He is calm, reassuring, authoritative.

They meet for one last time, and share a passionate afternoon together. However, when Costley takes control of the situation, Yvonne is plunged from one nightmare into another.

Yvonne's life is turned upside down yet again, when she is ripped away from her family and arrested for murder. In shock, Yvonne denies everything, but the police are convinced that she and Costley colluded in cold blood.

Their trial begins and very quickly Yvonne realises that everything she thought she knew about her lover was a lie.

And right now he's all that's standing between her and a prison sentence.

The murder trial continues, with Costley's defence resting on evidence of an underlying personality disorder.

But the prosecution barrister rips this theory apart and Costley's case seems to lie in tatters. Costley's back is up against the wall. Has he reached his tipping point?

And if the court find out that Yvonne lied about their affair, will they believe anything else she's said?
