'In Brisbane, single parent Kate Anderson, 34, drops her two youngsters at school before a routine visit to Lisa, an emergency housing client. A Queenslander, social worker Kate has rebuilt her life after divorce and enjoys her work supporting disadvantaged people. After being first to witness the gory scene following the brutal murder of Lisa and her children, Kate turns to her close-knit family for support. She meets Jack, her brother's solicitor friend and gratefully accepts his help, as the horrors multiply to engulf her. Suddenly and inexplicably, as she tries to piece the mystery together, Kate becomes the target of a prowler and telephone threats. Determined to find out why this is happening and feeling that the police are missing something, she ignores all warnings of risk to herself. Jack's assistance becomes increasingly important and although romantic entanglements are out of the question, Kate finds herself strongly attracted to him. Events escalate with another killing and when Kate's own precious children are kidnapped the stakes reach a new level. With the help of the police the children are rescued. Then when Prue, a work colleague disappears, Kate becomes bait to catch the killer.' (Publication summary)
