Private investigator Tess Grey's latest case involves tracking down Hayley Cameron, a young girl who has fled after discovering that she was adopted. Tess, aided by her fiancé Po Villere, traces Hayley to the apartment of Madison Toner - one of Hayley's college friends - in Bangor, Maine.

Despite Tess's pleas, Hayley refuses to return to her adoptive mother. Both Tess and Po believe there's more to her running away than it seems, especially when they see Madison's father bloodied and beaten. Concerned for Hayley's well-being, they conduct a stake-out.
