When a highly infectious disease breaks out with in the confines of the Cumberland State Correctional Facility, Special Agents Mulder and Scully are called in to find the cause of the epidemic, and put a stop to it.
Outside the prison walls, Mulder risks his reputation -- and his -- life to track down two escaped prisoners -- who may or may not be infected. Meanwhile, on the inside, Scully finds herself facing a full quarantine -- and set of doctors who are as silent about the situation as the bodies they are burning.
Can Mulder and Scully find the men before this plague claims more lives?
