William Avery is released after serving a prison sentence for embezzlement, but almost immediately dies in a car accident. Someone nevertheless begins to stalk his daughter, apparently believing that she knows where the missing money is hidden. Though Avery's daughter insists that her father was innocent, she hires Joe Mannix to protect her -- and Mannix concludes that the best way to help her is to re-open an investigation of the theft, to find out who from Avery's past would still want to find the missing funds.

When the show begins, William Avery (Fritz Weaver) is getting out of jail after serving 10 years for embezzlement. Someone is VERY interested in him and they begin following him. As he increases speed, so do they...and eventually Avery loses control and falls to his death. Oddly, however, most everyone assumes he's dead yet there's no body!

Soon after this, Anne Avery (Anne Archer) comes to see Mannix. Evidently, some unknown person or persons have ransacked her apartment and perhaps they were looking for the money her father had embezzled...though she KNOWS he didn't steal it. Soon, Mannix sets up one of the crooks to break in and uncharacteristically, he REALLY screws this up big time!! Eventually, folks start dying and Mannix not only has to save his client but possibly determine where this missing money is.

This is an enjoyable and inventive show and I am glad I saw it. I did have a few complaints here and there (the car explosion scene was handled sloppily and Mannix was too dumb trying to do a stake- out all alone...duh). Still, it's well worth seeing and reasonably unique.
