The estranged daughters of famed author Walter Briggs (Robert Vaughn) tell Sgt. Benson their stepmother is plying their senile father with Viagra and daily sex. They say Charmaine Briggs (Marcia Cross) is preventing them from seeing him and risking his life to conceive a child to get a bigger cut of his estate. Briggs brags about his youthful sexual prowess, but ends up having a heart attack. Dets. Carisi and Amaro block Charmaine from flying him to Canada against medical advice and court orders. After Briggs has a fatal heart attack, they discover Charmaine extracted semen post-mortem. ADA Barba charges her with murder, but after a video of the dead novelist surfaces, the real reason for the daughters' estrangement is revealed.

Meanwhile: Benson tries to hide the secret of Noah's biological father and Barba tries to get his grandmother into a nursing home.
