That's what Detective Sergeant Tony Carvelli thinks of Psi Cops until he's faced with a sadistic serial killer who leaves no evidence behind.

In a near-future St. Louis, after sexually-transmitted diseases have been eliminated and sex without commitment is a lifestyle for much of the population, Carvelli investigates the deaths of women dismembered in their own bedrooms. Carvelli still believes in the old values: love before sex and investigation before technology.

When Psi Cop Colleen Allison is assigned to the case against his wishesùthanks to his new partner, recently-promoted Detective Phil PalmerùCarvelli resents her and everything she represents.

Fighting against time and against each other, Carvelli, Palmer, and Allison struggle to find the killer before he strikes again.
