Unprecedented access to one of the country’s top law firms as they begin the public inquiry into the death of Sheku Bayoh, who died after contact with the police in 2015.

New evidence arrives at The Firm, and Aamer takes on the case of a man who died in hospital under unexplained circumstances.

The sister of Sheku Bayoh gives evidence to the public inquiry into his death. Meanwhile, Ryan meets with a new client who has little to no defence against his charges.

As Aamer returns to Liverpool to reflect on the case that made him, The Firm tackles the seemingly unwinnable case of a man that took self-defence too far.

The Firm prepares for the start of the long-awaited Scottish Covid Inquiry, and shock revelations hit the headlines.

As one of Aamer’s good friends Humza Yousaf becomes Scotland’s first minister, Aamer himself takes on the Prison Service in two very different cases relating to death in custody.

The Sheku Bayoh inquiry focuses on cause of death, which proves traumatic for the family. Aamer takes on the case of a police incident in which a refugee was shot dead.

Aamer is torn between his ever-increasing workload and his responsibilities as a father. An announcement from the Chief Constable of Police Scotland shocks Aamer and the team.
