El rastro

THE PYX opens with the death of a prostitute named Elizabeth Lucy (Karen Black). Dt. Sgt. Jim Henderson (Christopher Plummer) is on the case. What, at first, seems like a typical murder, develops into something that Henderson can't explain. As he digs deeper into the mystery of Elizabeth's death, he must face the possibility that occult forces are at work.

The atmosphere of this movie grows increasingly thick with gloom and dread. Ms. Black is quite good in her doomed role, as is Plummer as the dogged investigator. His facial expressions during the finale are perfect and unforgettable.

The music by Ms. Black is tragic and haunting...
