A serial killer is on the loose in San Francisco, and five victims--all women--have already been claimed. Ironside (Raymond Burr) suspects that the most recent killing was not committed by the same maniac who bumped off the previous four victims, but by a different person who was using the murder spree to cover his tracks. The episode's climax finds youthful policewoman Eve Whitfield (Barbara Anderson) donning old-age makeup to flush out the villain. ~ Hal Erickson, Rovi
