Tom is faced with a dilemma when a mother asks him to protect her son, a convicted felon who is back home after an early release. The boy was responsible for the particularly cowardly armed robbery of a local real estate office which traumatised the owner's wife so much that she later committed suicide. Her husband seems a reasonable man, but could he be harbouring feelings of revenge? Someone has to be responsible for the threatening phone calls and broken windows the family is getting. The Heelers question an old associate of the son's and, by chance, discover him to be in possession of a stolen police gun. The news almost immediately brings Detective Sergeant Ben Stewart, from Organised Crime, to Mt. Thomas. He has been on the trail of these stolen police weapons for the past two years, and is excited to have a positive lead at last. Ben Stewart fits in very well at Mt. Thomas—almost too well for PJ's liking as he takes an immediate shine to Maggie and wants to ask her out. Unable
