Subject: I want to believe

Mulder and Scully have been out of the FBI for several years — with Mulder living 
in isolation as a fugitive from the organization and Scully having become a doctor 
at a Catholic-run hospital, where she has formed a friendly relationship with a seriously 
ill boy patient — but, when an FBI agent is mysteriously kidnapped and a former priest 
who has been convicted of being a pedophile claims to be experiencing psychic visions 
of the endangered agent, Mulder and Scully reluctantly accept the FBI's request for their 
particular paranormal expertise on the case.
