Mulder and Scully return to the site of their first investigation together when a series of abductions take place. However, Scully’s failing health, and Mulder’s concern that she is in danger, cause him to take her off the case. Meanwhile, the Cigarette-Smoking Man - on his deathbed - reunites with Marita Covarrubias (Laurie Holden) and Krycek in an attempt to revive the project.
