Kate has already “disappeared” twice before (once to her Grandmother’s house & once to her father’s) so when her sister alerts the police that she’s missing again, no-one believes her! Kate has been kidnapped by a guy who saw the news reports about the other disappearances and thinks she looks like his long-lost daughter Lucy. Kate’s sister enlists the help of an ex-policewoman who puts together a psychological profile of the man after believing the sister’s story.[The part where Mr Larwood turns a little nasty in the kitchen]
