Undercover

For the past twenty years Maya Cobbina has defended Rudy Jones, a man falsely imprisoned for murder. Today he is to be executed by lethal injection in Louisiana. Rudy's parting words are "Go big" - hewants her to change the system that allows such injustices to occur.

With Rudy's appeal ringing in her ears, Maya returns to London and discovers that she's been pegged to take the role of director of public prosecutions, a prominent position that might allow her to finally bring to justice the death of her friend Michael Antwi, a charismatic anti-racism campaigner.

Maya's husband Nick Johnson is a man dedicated to his wife and children. When a hidden past threatens to destroy his world, to what lengths will he go to protect his family?

As Maya continues her fight to ‘Go big', the establishment begins to fear the rigorous light she threatens to shine on areas they would prefer remained in the shadows.

Sickened by his act of betrayal, Nick can only reflect on the actions that led him to this point. A flashback reveals Nick in 1996 as a fearless undercover officer. When his hard work is undermined by a radical young lawyer, Nick is furious. On his next assignment, spying on an anti-racist organisation at a seemingly peaceful march, he finds himself face to face with the lawyer, Maya.

The march gets out of hand and Michael Antwi is attacked in a ferocious fight. Nick's feelings for Maya develop and he struggles to keep the professional and the personal separate, questioning his own beliefs, as a black man within the police force.

A mystery witness makes contact with Maya, forcing her to re-examine everything she thought she knew about the Michael Antwi case. What has she missed? Maya must put the past to one side in order to fight the US authorities, but her return brings a disappointment and a revelation that will rock her marriage to the core.

Terrified that Maya might be close to discovering his secret, Nick controls the situation with a devastating lie.

Taking solace in work, Maya continues to search for the witness. What had Maya missed all those years ago? Far from shining a light on the case, her investigation leads to a shocking fact that forces her personal and professional life to collide. Maya makes a call she knows might change her life forever. Who is her husband?

Meanwhile, Julia stumbles across a story that seems more than a coincidence, and begins to dig deeper into the background of a mystery woman. Despite her efforts, she falls short – who was she and why is she so hard to track down?

As Maya continues to fight the US authorities, all seems lost until new evidence emerges which might prove Rudy's innocence once and for all. Spurred on to discover the truth, Maya must go bigger - but is it too late?

Following the death of Rudy's alibi witness, Maya's case is in tatters and her cards seem all played out. Can she find the strength for the final fight and change the course of US Justice?
