Sprats and Mackerals

A rumor causes Thamesford task force to investigate at Eastcote docks where someone allegedly brings illegal immigrants into the country. WP/DC Betty Donald goes undercover, posing as a juvenile delinquent, while Sergeant Jackson receives an undercover assignment at a nearby camping site. Soon the investigation turns into a run against time when a bunch of abandoned illegal immigrants need to be located before they end up dead.
