When a spine is dredged out of Whitney Marsh, a new case begins for Jess and Sunny’s team at Bishop Street CID. Four potential suspects soon appear, each with secrets to hide.

The Bishop Street team investigate the deceased's record, relationships, and enemies, and Jess and Sunny make contact with his widow. No one is as innocent as they first seem.

The team discover Asif, Mel, and Marty’s connections to the deceased, and bring Marty in. Secrets from the deceased's past come to light, and Jess reaches out to her sister.

With the details of the deceased's life becoming clearer and one suspect already being questioned, the Bishop Street team find suspects further afield.

For better or worse, Jess and Sunny finally get the truth from Asif, Marty, Mel, and Juliet. But both on and off the case, the truth leads to difficult decisions.
