Sergeant Miller is "off to learn the patch" as he calls it when he spots a speeding car and give chase, but the driver, David's Aunt Peggy, easily manage to lose him, ruining his day completely. It will not be the last time she does that and their relation will soon be just like the one between Oscar Blaketon and good old Claude Jeremiah Greengrass. Rob Walker has been dating the nurse Clare Owen since she took care of him after he crashed on his motorcycle. They are both invited to a party celebrating the arrival of a new doctor at the hospital, Gavin Kennedy, who coincidentally also Clare's former lover. During the party another of Clare's colleagues does the high wire under the influence of drugs and alcohol and is seriously injured when he falls to the ground although Walker tries to stop him.
