Enigmatic, unrelenting and charismatic, we follow DCI Gabriel Markham as he is propelled in an obsessive hunt for a serial killer who left a mark on him both physically and mentally. As the clock ticks back, and Gabriel's personal and professional lives unfurl, we explore the painful psychology of a man disfigured, while the shock waves from the crime ripple out in reverse. Alongside a thrilling chase to catch a brutal killer, Rellik explores the very nature of motivation, as we delve deeper into the past to uncover the events that shape a person into who they will become.
