Saving deceased gangster Jack South's daughter Nikki from an attack by hired thugs earns "minder" Terry McCann a trip for two across Europe on the famous Orient Express. But a perfect romantic opportunity with his girlfriend Annie is ruined when his dodgy employer and "friend" Arthur Daley cons his way onto the trip to avoid a court appearance, and Terry again finds himself battling to protect Nikki from a whole train load of sinister characters all after Nikki's legacy. Add to this a Mafia hitman, a gun-toting Interpol officer and an unwelcome appearance by Terry and Arthurs' London nemesis, the long suffering Detective Sergeant Chisholm.
