Landowners try to drive a group of hippies off their land but a young boy is injured and taken to Holby where the staff have problems, dealing with the trouble they bring. George recovers from his overdose and is impressed with Brendan. Peter turns up and Duffy tells him she was worried about him and tells him her test is clear. The drugs cabinet's been broken into and a rookie cop gets bitten on the leg by one of the hippies and has to have a tetanus shot. Peace is restored when the hippies leave.
