When a child goes missing at the local tennis club on the same day that several skeletons are unearthed on a building site, Fran Harman's caseload is heavier than ever. Enjoying a game of tennis when the girl disappeared, Fran's partner Mark blames himself for not keeping an eye on her. Sucked into the kind of desperate police search he thought he'd left behind on retirement, Mark enlists the help of his fellow Golden Oldies to find young Livvie before it's too late. Meanwhile, a further shocking discovery suggests that a serial killer may be lurking.
