Season 3

One daughter's tragic murder rocks a dysfunctional family's world. A second daughter descends into madness by the death, coupled with a ferocious custody battle that drives her into a homicidal rage.

The Plummer sisters' tight relationship unravels with a series of suspicious arsons and a missing inheritance. Then one sister falls ill, while her estranged sibling coldly witnesses her slow, painful death.

A custody battle turns deadly as twin sisters craft a complicated, cross-country conspiracy to eliminate the one person standing in their way - as the children look on in dismay.

A disabled Florida woman is cared for by her sister in relative peace for four decades until a life-changing event decimates their relationship, and the result is murder.

A hit-and-run car accident might not be an accident, after all.

Two sisters, with little in common, cope with their overly protective mother in very different ways and with very deadly consequences.
