May 1988. Detectives investigate the discovery of the body of 86-year-old Alice Covington inside her car outside the city of Raleigh, North Carolina. The remote location and the 'vampire-like' burn marks on Covington's neck immediately raise their suspicions. Investigators hit the streets for clues. They learn the elderly woman was seen struggling with a female nurse before she disappeared. A bank-teller reports she cashed a $2500 cheque on Covington's account when she and a nurse pulled up at drive-thru bank. Detectives question Covington's friends and identify homecare nurse, Carlette Parker, as the prime suspect responsible for her demise. When they research her background, they discover she has a history of stealing from those in her care.
