Synopsis: Each episode in this suspenseful new series will investigate an everyday American family’s darkest mystery, aiming both to solve the mystery and explore how it shapes that family today. Colorful characters, rich cultural context and dramatic twists and turns abound in every tale, each of which connects the American family to their UK heritage. Along the way, we’ll meet charismatic heroes and terrifying villains, ranging from a 99-year-old World War II veteran who worries his absence led to the murder of his grandmother, to the daughter of a serial killer desperate to carve out her own identity from her father’s sordid past to a mother who abandoned her three children to start a new secret life.
