This episode of The Rockford Files has James Garner making a visit to the old homestead, the state prison where a con played by Eddie Firestone wants to hire him to find an old girlfriend. Rockford says no, but in a week Firestone is out and brings money in the form of a cashier's check. Rockford as always is having cash flow problems.
Of course it's a given that there's more to why Firestone and his old running buddy Burr DeBenning want to find Mary Frann. It's a valuable necklace she has. I can't go into it, but they pull an elaborate sting like con game on Jim Rockford which he's just a tad too late to figure out and he's given a big headache and a police APB on him for a jewel theft.
Fortunately Rockford has a friend useful in situations like these. This episode proves why Rockford puts up with Angel Martin. Garner and Stuart Margolin pull their own sting to wrap things up.
Any Rockford File episode with Stuart Margolin is just that much more special. This episode is no exception.
