When gangster Jack South passes away, he leaves his young daughter Nikki with some ambiguous clues about the location of his ill-gotten gains hidden away in a Swiss bank. Coming of age, Nikki is legally able to discover the remaining clues to where the money is actually stored away, with Jack South’s ex-wife (Nikki’s stepmother) and a string of former business partners hot on Nikki’s heels all believing they are entitled to a piece of Jack South’s fortune. As Nikki is attending her birthday party at the ‘Roseberry’s’ club at which Terry is working, she is mugged by those looking for the information she holds and Terry bravely interrupts the mugging to help her out. Meanwhile, while Arthur was delivering a microwave to ‘Bozz’ Boswell, he bore witness to intimidation as part of a protection racket from local gangster Brian Gamage, known locally as ‘Brain Damage’ due to his violent tendencies. When Rycott and Chisholm discover Arthur was there during the incident, Arthur is subpoenaed in order to give evidence against Gamage, which he tries to avoid at all costs, especially as Gamage has found out about the subpoena and has sent his heavies around to warn Arthur it could be very bad for his health.
Realising that Terry is someone she can trust, she offers Terry and his girlfriend Annie two tickets to a trip to Switzerland on the Orient Express, with Terry completely unaware of Nikki’s real intentions for wanting him on board. With Arthur now keeping a very low profile and doing his best to avoid the subpoena and Gamage’s men, he realises that a trip away on the Orient Express with Terry might be the solution to his current dilemma. Arthur lies to Annie and tells her that Terry’s wife and children have returned and as a result swindles his way on board the train, much to Terry’s disgust as he was expecting a nice trip away with Annie. While on the train, Nikki tells Terry the real reason why she gave him the tickets and Arthur, Terry and Nikki soon discover there is no one on the train they can really trust as they all have some connection with Jack South or his legacy of crime – the only partial exception to this being Chisholm who has ended up on board by pure accident, seconded to work with Interpol for a limited period as an observer. Chisholm has his own problems on board as he realises Arthur and Terry could seriously compromise his position as he finds himself out of pocket with the expensive prices on board the Orient Express.

Bloopers: At 18m18s, when Terry is going to collect Mr. Roseberry’s car, his girlfriend Annie asks the club’s visitors if they are with Miss West’s party. At 20m30s, the same two visitors are then seen sitting beside Nikki South at her birthday party table, so the name West was obviously confused with South somewhere in the script.
