Today's sequel is 1991's SILENCE OF THE LAMBS (follows 1986's MANHUNTER).
Young FBI agent Clarice Starling is assigned to help find a missing woman to save her from a psychopathic serial killer who skins his victims. Clarice attempts to gain a better insight into the twisted mind of the killer by talking to another psychopath Hannibal Lecter, who used to be a respected psychiatrist. FBI agent Jack Crawford believes that Lecter, who is also a very powerful and clever mind manipulator, has the answers to their questions and can help locate the killer. However, Clarice must first gain Lecter's confidence before the inmate will give away any information.
