Florance 'Flo' Lowell, a mother to questionable three kids, a bookshop owner, a former part-time consultant to the HPD – and occasionally, a psychic – finds herself back in the deep end as a spirit comes to her with the need to reopen a cold case despite her determined retirement from the force years ago.

Roberta 'Bobbie' Rhodes, a New Jersey born detective, leaves for Hawaii after losing her work partner to a vicious, unfair case. She plans to bury her head in impossible cases and forget the past.

Unfortunately, faith – or her Captain – has different plans for her as he finds a particularly strange case for her to solve.

A serial killer, an old case, and a psychic claiming to have answers from the dead. A couple of ghosts, and oddest second chance at life and possible romance she'd ever expected herself to be found in.

She just knew her former partner was laughing at her from beyond the grave.
