La Femme Nikita (1997)

Season 3: Episode 15

This time, Section is out to get an outfit by the name of The Alliance, and Section's way in is a psychotic courier by the name of Jan Bailin. Bailin has other plans and she kills herself before the Section can use her. So, as a backup, Section employs a meek, terminally ill lookalike for Bailin by the name of Sarah Gerrard. As she trains her, Nikita starts to get suspicious, did Section purposely make Sarah ill to make it easier for Section to convince Sarah to work for them? And if so, will Section even let Sarah live if she completes the mission?
