The Hidden (1987) | Jack Sholder

Michael Nouri stars as LAPD detective Tom Beck, who takes down a bank robber gone berserk in one of the bloodiest shootouts in department history.  What Beck doesn't know is that the culprit is actually being controlled by a parasite within his body that loves danger, money, speeding, and good ol' rock-n-roll, and it can't be killed by normal means, and moves from host to host whenever the body it is in is about to expire.  Enter FBI agent Lloyd Gallagher (Kyle MacLachlan), on assignment from Seattle to help apprehend the perpetrator(s) on a killing spree the likes of which have the LA cops stymied.  Gallagher seems to hold the key as to why normally good people are going bad all of a sudden, but he's not letting on why.
