Informed by Buxton that the 'other side' are plotting to kill the Commander, Briggs goes undercover as a restaurant waiter and ends up saving the Commander's life - but nor before he lands himself, and gun, in the soup.

Having tracked to a heliport two Russian agents suspected of organising escape routes to Moscow for agents on the run, Briggs accidentally switches on the airport's Tannoy system - and broadcast his plans to capture them.

While attending a cocktail party with his wife, Briggs saves the day handing a roll of 'classified' film to an enemy contact - the man believes he's getting film of a secret missile base but Briggs accidentally hands over his holiday film.

Assigned to discover who is behind an escape route, Briggs find himself swimming in muddy water but nevertheless stumbles across the ringleader - and accidently rounds up the gang single-handed.

When the Commander is abducted and Briggs is left to engineer his escape, the agent does so, but not until he has bumbled his way through another mission and driven the abductor's getaway car - and the Commander - to safety.
