Lawyers Ben Graham and Alisha Cole are a happy couple whose world is rocked when they accidentally glimpse a moment of injustice. Drawn into an underbelly of corruption and conspiracy, they try to report what they have seen but find themselves enemies of the state. Determined to put things right, Ben and Alisha set up an agency to support whistleblowers: people who refuse to turn a blind eye to corruption and will risk everything to expose the truth.
