Datta and Jarvis try to track down a missing girl whose mother fears she has been kidnapped. Datta initially suspects the mother may be fabricating stories about the child's supposed abduction, but later realises that her fears are totally founded. Suspecting that the young girl may have wandered off with her elderly minder, Betty, Datta and Jarvis manage to track them down at a local park, only to find Betty has died.
