Police officer Candice Renoir returns to France after ten years abroad. When a woman is found dead on the seashore, she discovers the victim has a double life.

A young man is found dead lying next to his barbecue; Candice's children have trouble adjusting to their new life.

Candice works on the case of a teenage boy who is assaulted and thrown into the harbour while having problems with her teenage daughter Emma.

The police find a young woman's body at a landfill and Candice recognises her as a prostitute she met on a previous case.

Candice is forced to cut a romantic date short to deal with an emergency at a local hotel; someone arrives out of the blue to make Candice's life even more difficult.

The children are pleased by the unexpected visit of their father, but Candice is not. A former expatriate is found dead in her car.
