Hijackers (S01E05)

Nature resembles a battleground, with parasites as its fiercest warriors. Insatiable and merciless, these organisms disregard any boundaries. They have developed numerous tactics to take over their hosts: some feast on the food within the intestines, others inhabit the bloodstream, draining vital nutrients, while some even invade the brain. This episode uncovers some of the most chilling instances of parasitic infections across the United States. In Virginia, a terrifying creature is on the loose, targeting an unsuspecting child. Meanwhile, in Michigan, a deadly invader infiltrates a traveler's bloodstream, and a peaceful day at a Florida lake spirals into horror when a relentless monster strikes a young boy's brain.
