Sweet Sixteen

The Ashfordly station is targeted in a series of violent attacks ahead of an inspection, putting one of the officer's lives at risk and causing a panicked Craddock to take matters into his own hands. Meanwhile, Tricia finds herself in trouble with a horde of angry parents when she prescribes a contraceptive pill to a 16-year-old girl. Elsewhere, Vernon and David fall out when strange events occur at the cottage, until they discover they have a new house guest, whilst Bellamy moves in with a depressed Mike after Jackie's departure.
