PC Duggan appeared at Home Farm after Lachlan White makes an anonymous phone call to the police that someone had messed with grandfather Lawrence White's medication. Lawrence suggests to Duggan that his daughter Chrissie's estranged husband Robert could be the one responsible for messing with his medication. Although it is really Lachlan who messed with it to frame Robert. Duggan and a colleague turn up at the B&B and take Robert in for questioning.
