"Five Days," according to press notes, "revolves around the mysterious disappearance of a beautiful young mother in the family-friendly suburbs of Hertfordshire, outside of London, and the strange, inexplicable circumstances that leave her children abandoned far from home. Focusing on the day of the woman's vanishing and four random days that follow, the story traces the ripple effects felt by her family, the police and the media during the course of the 72-day investigation. The miniseries presents an eerie picture of modern life in southeast England, where stately homes of multiple generations co-mingle with modern architecture and the throbbing new beat of a city in flux, and where a family's life-altering trauma becomes not only a complex police investigation, but ripe fodder for tabloid headlines."
In a statement HBO Films president Colin Callender said, "'Five Days' is a brilliant piece of writing that goes the behind the scenes of a tabloid crime and explores the emotional impact on the family of the victim and the investigators. Each of the five hours captures a watershed day in the investigation and its fallout effects on the lives of those involved. We are thrilled to be a part of this intriguing project and continue to enjoy our creative collaboration with BBC."
