Clint Eastwood plays a New Orleans detective determined to track down a serial killer of prostitutes. Complicating matters is the fact that the unknown culprit is very likely an S&M fetishist....and so is Eastwood.
The detective is profoundly disturbed at the likelihood that he and the killer have the same taste in women; this element of the case is equally troublesome for psychologist Genevieve Bujold, who finds herself attracted to Eastwood.
The climax involves the killer's attempting to throw Eastwood off the track by kidnapping one of the detective's two daughters (played quite well by Clint's real-life daughter Alison).
Despite its reliance on bloodletting, particularly in the final scenes, Tightrope is most effective when probing the hangups and vulnerabilities of Clint Eastwood's character.
