When one of her pupils, Cefin, is found dead, the case reopens the unsolved disappearance and death of her niece Nessa. Jackie joins her old police partner Eric Bull and his new detective partner, Jess Deng, while a huge storm threatens to flood the town. Their search uncovers family secrets, guilt, and a cover-up linked to the sea wall. The storm and rising water remain present as the town tries to protect itself and keep the murder evidence safe. Osian warns about poisoned air and water, and says people should not have children because the future will be hellish. Jess pushes back when Bull sidelines her, then takes more control of the case. Bull's relationship with Gareth brings a gay male couple into the story. Jackie faces an unexpected pregnancy and begins to welcome motherhood.
