Cannon (1971)

Synopsis
William Conrad stars as corpulent private eye Frank Cannon in this 2-hour pilot for the subsequent Cannon series. He responds to a plea for assistance from ex-flame Vera Miles (an actress who was in practically every pilot film made between 1965 and 1975). She is the prime suspect in the murder of her husband, and has also become the target of vicious anonymous phone calls. Cannon's investigation unearths a hotbed of small-town corruption. Cannon was first telecast March 26, 1971. ~ Hal Erickson, All Movie Guide
