Just as her life comes under intense public scrutiny Maya discovers that her husband and the father of her children has been lying to her for years. Is he concealing an affair, or is it something altogether more sinister? If she digs up his real past will she be safe and who wants her in this job and why?
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" - he wants 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', members of the establishment begin to fear the rigorous light she threatens to shine on areas they'd prefer to remain in the shadows. Elsewhere, sickened by his act of betrayal, Nick can only reflect on the actions that led him to this point. We join Nick in 1996 as a fearless undercover officer. When his hard work is undermined by a radical young lawyer, Nick is furious. Soon after he finds himself face to face with the lawyer, Maya, on his next assignment - spying on an anti-racist organisation. Nick struggles to keep the professional and the personal separate when his feelings for Maya develop and he questions his own beliefs as a black man within the police force. When a seemingly peaceful march gets out of hand, Antwi is attacked in a ferocious fight. Can he survive?
A mystery witness makes contact with Maya, forcing her to re-examine everything she thought she knew about the 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'll rock her marriage to the core. Nick is thrown sideways when a ghost from his past approaches him. Faced with the possibility that his secret life is going to be blown open, Nick makes a fateful decision to protect his family. Meanwhile, in 1996, the efforts of Maya's journalist best friend to shine a light on the Antwi story is thwarted, illuminating the lengths to which the establishment will go to protect their own.
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 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, but despite her efforts she falls short. Who was she and why is she so hard to track down?
Maya's trust is in tatters, but all her cards are played out. Can she find the strength for the final fight and change the course of US justice? And when the final piece of the jigsaw that links these two miscarriages of justice is revealed, what does that mean to her fight to 'go big'? Facing the end of his marriage, Nick concocts a drastic final plan with the help of Julia and Brady to expose the establishment figures responsible. In the aftermath the people really responsible for the growing conspiracy are finally exposed, but not all are as fallible. As Maya picks up the fragments of her life, is there a way forward for her family, and can she come to terms with a truth she could never have imagined?
As Maya continues to fight the state authorities, all seems lost. Until a stranger appears with new information that forces Maya to question her understanding and uncover links between her two cases. Spurred on to discover the truth, Maya must go bigger, but is it too late? Nick's secret is threatened by someone close and he can only watch as a vital piece of intelligence is revealed that could destroy Maya's work. Is there any way back for the family? Meanwhile, Julia and Brady dig deeper and uncover the truth about Nick. Just how deep into the establishment has the conspiracy spread?
