Reclusive ex-soldier Sam Griffin is unnerved when a body fished out of Porth Madryn docks one chill October Morning is identified as his.  The event triggers a deadly series of events that draws him deep into a criminal world he never knew existed.

Something's wrong with aging gangland boss, Leon Vicary. Henchman Eddie Mulheen aims to find out what.

Grace drops in on her daughter Rhiannon's 18th birthday party to give her a car as a present. But she finds no party, no guests, a luke warm welcome from her daughter and more questions than answers.

Business is brisk, but Rhiannon is becoming concerned that things are beginning to get out of control. She needs back up, but who can she turn to?

Tom Griffin's body in the mortuary has a visitor.

Grace is anxious to know if Professor Meurig Lewis had done the right thing before he died, and wonders why her daughter Rhiannon has so little interest in her father's reappearance.

Eddie pays a visit to Grace who's eager to know if she can count on his support for a coup.

Vicary decides to get to know Sam better, but is he running out of time?
