At the Saint Ignatius Orphanage, a rebellious boy named John Rossi refers to himself as “Simon Templar” and leads a group of fellow orphans as they attempt to run away to escape their harsh treatment. Just as Simon is caught by the head priest, he witnesses the tragic death of a girl, to whom he had taken a liking, when she accidentally falls from a balcony.
As an adult, Simon (Val Kilmer), now a professional thief dubbed “The Saint” for using the names of Catholic saints as aliases, steals a valuable microchip belonging to a Russian oil company. Simon stages the burglary during a political rally held for the company’s owner, Ivan Tretiak (Rade Šerbedžija). Tretiak is a former Communist party boss and a billionaire oil and gas oligarch who is rallying support against the Russian president. Simon is caught in the act by Tretiak’s son Ilya (Valery Nikolaev) but escapes with the microchip. After learning of the heist, Tretiak contacts Simon and hires him to steal a revolutionary cold-fusion formula discovered by U.S. electrochemist Emma Russell (Elisabeth Shue). He wishes to acquire Emma’s formula—which creates clean, inexpensive energy—so he can monopolize the energy market during a severe oil shortage in Russia.
Using the alias “Thomas More”, Simon poses as a Boer traveller and steals the formula after having a one-night stand with Emma. Tretiak learns Emma’s formula is incomplete and orders his henchmen, led by Ilya, to kill Simon and kidnap Emma in order to obtain the remaining information. Heartbroken, Emma reports the theft to Inspector Teal (Alun Armstrong) and Inspector Rabineau (Charlotte Cornwell) of Scotland Yard, who inform her Simon is a wanted international thief. Emma tracks down Simon to a hotel in Moscow and confronts him about the theft and his betrayal. The Russian police, loyal to Tretiak, arrest Simon and Emma. However, they manage to escape from the police van as they are being brought to Tretiak’s mansion.
