DI Jack Frost investigates a series of burglaries directed against old age pensioners. Things take a serious turn when an elderly woman is badly beaten. On examination however, this case doesn't fit the pattern of the others and may not be related. As well, the victim was very difficult and disliked by many, including neighbours and community volunteers. The case takes a nasty turn when another elderly victim is found dead, with the potential to create a panic among the public. Frost concludes that the second victim knew her attacker and proceeds to eliminate all possible suspects, one by one.
