A diplomatic courier carrying deadly cargo involves Agents Mulder and Scully in a dangerous web of intrigue, which leads Mulder on a trip to Russia where he discovers an elaborate test being performed by Russian scientists.
Tunguska is a pivotal episode in the X-Files series, as it further explores the role of the Black Oil in the show's mythology. Moreover, we learn that the conspiracy of hiding the existence of extraterrestrial life is in fact global and that the Russians are experimenting with the black cancer in prisoners.
The special effects for this episode are very impressive, I love the way the black-oil worms were made and I liked the last image of Mulder being captured and the black oil worms crawling in his head and through his eyes. I also loved Krycek's return and Skinners reaction. Tunguska is a suspenseful, thrilling episode that should not be missed!
