Four Lives
DVD, out Monday 14 February
This three-part drama, which aired on BBC1 recently, tells the devastating true story of the botched police investigation into serial killer Stephen Port (Stephen Merchant), who killed four young men between 2014 and 2015. It focuses on the relatives of the victims – played by the likes of Sheridan Smith and Jaime Winstone – and their fight to see Port’s crimes investigated properly.
