Ex-KGB Colonel Gradsky (Lev Prygunov) and his men are also passengers, as are Nick, Natasha and Craig Warner (Michael Sarrazin), yet another unemployed spy, this time formerly with the CIA.

Though the plane runs out of fuel and has to set down 300 miles from the train's next stop, Harry and Nick just barely manage to get back aboard the Bullet.

Finally, Harry guesses that Alex is selling the Alorex to the North Koreans for heroin, a specialty of Craig's.

At the North Korean embassy, Palmer meets another old spy acquaintance, Kim Soo (Burt Kwouk).

He burns the valuable but deadly information and tips off both a rival gangster and the police about the incoming heroin shipment.

Complications arise when there is an attempt on Harry's life by men working for Kim Soo, which Craig surprisingly foils.
