Blood Relatives.

From the outside, families seem like harmonious units in loving homes. But you don't necessarily know what secrets families are hiding from the outside world. Narrated by actress Brenda Strong, the voice of Desperate Housewives character Mary Alice Young, this series explores families hiding the most extreme of family secrets: murder. Each episode explores a death in a family, unravelling the motives of the family members, all of whom are potential suspects - and potential victims.
