Officer Abigail Hale is adamant to re open a 7 year old case to find a missing girl from Waikiki. 7 years ago, Lucy Marino- aged 7, and Lilly Hale - Aged 14 both went missing from there homes in Waikiki. It was an ongoing investigation until a month later, Lilly Hales body was found on the north shore. HPD classed both victims as dead and ruled it as a homicide, but never found the killer. Now that Abigail has graduated from the Academy and is apart of the Honolulu police department, shes accessed the old case files and has new evidence to believe that Lucy Marino might still be alive and living on the island. Officer Hale needs a higher ranking officer to re open the case, and who better then commander Steve McGarret, a softy when it comes to personal cases and missing children. Alongside Five0, Officer hale picks up where the HPD left off years ago.
