Tony Baretta (Robert Blake) goes undercover to locate a vicious rapist-murderer. What he doesn't know is that the perpetrator is posing as a cop. The outcome of the investigation may well rest in the hands of a deaf-mute shoeshine boy (Charlie Martin Smith). Featured in the cast is Spencer J. Milligan, definitely cast against type for those who remember him as the kindly family man in the Saturday-morning fantasy series Land of the Lost. ~ Hal Erickson, Rovi
