La Femme Nikita - Season 1 Episode 20

When Nikita is sent to investigate a bartender at a posh club who may be a terrorist contact, he responds to her questioning by leaping from the 65th floor window to his death. A search of his apartment turns up a strange helmet-like device, which Section later discovers is used for brainwashing. Unfortunately, Nikita has used the device several times in an effort to discover what it is, and now it is in control of her mind. When Nikita and other operatives are assigned to protect the Premier of China from other similarly brainwashed individuals, Section has no idea that the greatest threat to the Premier is Nikita herself.
