Glaze is outraged when Clarke falls asleep on an obbo watching the Borrovitch brothers, who are suspected of running a protection racket. Taviner and Clarke then investigate the theft of stolen diggers on a building site. The main suspect is Mick Abbott, an occasional employee at the site, and when they visit him in the bus where he lives, his wife reacts angrily and attacks Clarke. Desperate to clear her debt, Clarke begins moonlighting in telesales at her flatmate's company. While out at a bar with her new co-workers, she spots the Borrovitch brothers, allowing Glaze to make a connection with the stolen diggers and German arms dealers, and a successful raid sees all the culprits behind bars.
