When a spate of bomb hoaxes begins to threaten peace and harmony in Sun Hill, Brownlow becomes eager to find the hoax callers and stop chaos from breaking out. Meanwhile, Galloway bets Cryer he is the perfect man to solve the case, recruiting Roach and Dashwood to help him. Cryer gives Carver the responsibility of showing a newly qualified officer, Higgins, the ways of Sun Hill - but a run-in with a local drunk who later accuses Carver of stealing his wallet leaves every officer on the uniform relief wondering if Carver is capable enough to do the job without bringing the social aspect into disrepute.
