Thamesford CID is investigating some cases of highway piracy. The robbers focus on lorry loads containing whiskey. The prime suspect is a Scottish lorry driver who seems to be involved in the crimes. When WP/DC Betty Donald volunteers for an undercover assignment posing as a prostitute to win the suspect's confidence, she soon discovers the risks her job entails - the hard way.
