Showtrial

When a climate activist is left for dead after a hit-and-run, he uses his dying words to name his killer – a serving police officer. With the country divided, will defence solicitor Sam Malik take on the trial of the decade?

As Southgate builds his case against Justin, attention turns to the D4 police chat group. With phones wiped and Justin's fellow officers saying nothing, D4 could hold the key evidence. Meanwhile, unable to sleep, Sam embarrasses himself at work. Can Southgate crack D4 and use Sam's lapse in focus to secure a charge?

With the trial approaching, Justin on remand and violence on the streets, the pressure on the legal teams is intense. Struggling with Justin's volatile personality, his own insomnia and an absence of medication, Sam reaches breaking point.

The trial begins, with battling protestors outside the courthouse. As the prosecution lay out their case against Justin, Sam and barrister Grainne pick holes in their evidence. But their biggest challenge may come in the form of Justin himself. Can Sam keep his dangerously unstable client under control?

As the trial resumes after Justin's shocking outburst, he finally takes to the stand and the question is put to the jury: is Justin Mitchell mad or bad? With Felix pointing to a bigger picture and the public baying for blood, Sam tries desperately to save his client. What choice will the jury make?
