Ep 13. Aboard the Orient Express

Maxwell Smart, a bumbling secret agent for CONTROL, is sent on a mission to protect a government courier carrying a top-secret document on board the Orient Express. The courier, Agent 32, is not told what he is carrying, but both he and Smart know that KAOS will stop at nothing to get their hands on it.

As they board the train, Agent 32 is immediately targeted by a KAOS agent disguised as a waiter. Smart, disguised as a British gentleman, tries to intervene but ends up knocking out the real waiter by mistake. Meanwhile, KAOS agents plant a bomb on the train and cut the telephone wires, trapping all the passengers.

Smart and Agent 32 try to figure out who on the train is a KAOS agent and who can be trusted. They enlist the help of a beautiful woman named Hester, who claims to be a journalist but is actually a KAOS agent. Hester, who is secretly working with the KAOS agents on the train, tries to seduce Smart and distract him from his mission.

As the train hurtles through Europe, Smart and Agent 32 narrowly escape several attempts on their lives. They discover that the top-secret document is actually a formula for a new type of fuel that could revolutionize transportation. KAOS wants the formula to use for their own nefarious purposes.

Smart and Agent 32 finally narrow down the suspects to a group of six passengers who are all involved in the fuel industry. They set a trap for the KAOS agent by inviting all the suspects to a secret meeting in the dining car to discuss the formula. Smart and Agent 32 reveal that the document is a fake and that the real formula is in their possession.

The KAOS agent reveals himself and a fight ensues. Smart and Agent 32 are able to defeat him, but not before he detonates the bomb on the train. They manage to stop the train and evacuate the passengers before the explosion, saving everyone's lives.

In the end, Smart successfully delivers the real formula to his superiors at CONTROL. Hester, who had fallen in love with Smart, is arrested and taken into custody. Smart and Agent 32, having saved the day yet again, depart the train as heroes.
