Four Lives

Three-part BBC drama starring Stephen Merchant as serial killer Stephen Port.

When two young men are found dead in East London, the victims' families immediately suspect murder despite the police attributing their deaths to drug overdoses.

When the bodies of more young men are discovered in the area, attention begins to fall on Port, but the Metropolitan Police remain reluctant to declare a murder inquiry.

As the victims' families conduct their own research the official police investigation comes under increased scrutiny.
