The outbreak of a grotesque plaque in a prison traps Scully in the path of an epidemic as Mulder chases escaped felons who may be carrying the disease into society.

U.S. MARSHAL TAPIA: Well, then you'd be a real big help is you just tried to...stay out of the way. MULDER: Well, we'd be happy to, soon as we can talk to someone who's in charge... TAPIA: I'm in charge here. MULDER: Apparently not, or you'd know why our involvement was requested. SCULLY: Where are you going? MULDER: To see if I can get in the way. CIGARETTE SMOKING MAN: Then you don't know much, Agent Mulder. CSM: The truth would have caused panic. Panic would have cost lives. We control the disease by controlling the information. MULDER: You can't protect the public by lying. CSM: It's done every day... SCULLY: There'll be a time for the truth, Mulder, but this isn't it. SKINNER: Agent Mulder. I'm saying this as a friend. Watch your back. This is just the beginning.
