20 parts Complete 5 years ago, Hannah Parker was murdered while out for a morning jog to the stores and back to get some groceries for breakfast with her family. The killer was never found.
Now, aged 23, Sophie Parker is called back home. The murderer is still out there, and he has gotten in touch with the family.
Terrified for his daughter's safety, Daniel Parker employs the services of Swift & Kyle Private Detectives and Security Services, rumoured to be the best in the business.
He is surprised when the youngest associate, Nathan Swift, who only has experience in handling data-bases, is sent.
But he lets the quiet, serious youth who perhaps is the only man who doesn't fall for Sophie's quiet demeanor and gorgeous face and who doesn't get madly turned on by her younger sister; Alexis, stay on.
Will the quiet stranger have what it takes to outsmart the murderer? Or will the rest of Hannah's beloved family follow her fate?
