Maggie Wise, a retired homicide cop turned radio presenter, is asked to help the local police with the case of two missing girls.

Dr Oscar LeBlanc is close to a medical breakthrough to cure dementia and other degenerative diseases . . . but in order to succeed he needs to illegally obtain plasma from prepubescent children. He believes the ends justify the means and two young girls are abducted.

The disappearance of the girls causes a lockdown of the area and, when one of the girl's parents prove uncooperative with the police, former homicide cop turned radio presenter Maggie Wise offers to help. Maggie quickly forms a connection with the family just as the girls are recovered.

LeBlanc is quickly suspected, but after he is questioned he's found dead from an apparent suicide. However, the circumstances are suspicious and Maggie finds herself conflicted when the family become the prime suspects.
