The Colliers fought for their lives - but never had a chance against their granddaughters rage. Soaked in blood, Holly and Sandy took off in the Colliers' truck. When police arrested them, Holly had a to-do list written in pen on her arm- Kill, keys, money, jewellery . The girls' lawyers battled furiously for an acquittal. Then it was up to a jury to decide- What price would they finally pay for their love, their rage - and their evil?
