 Sophie is given a brutal introduction to the realities of police work when she s first on the scene of a hit-and-run jet-ski accident that results in a young water-skier dying in her arms. Unwilling to show what she thinks are signs of weakness, Sophie pretends to be unaffected by the girl s death and avoids Jack s attempts to discuss the matter. Alex too, is moved by the girl s death, causing disturbing memories to resurface for her, as she and her mother were once the victims of a hit-and-run driver. Alex s eventual capture of the jet-skier responsible will put a new perspective on the guilt she has been carrying over the accident.
