Baretta's best friend, a parole officer, is murdered after telling Baretta that a model who supposedly killed herself months earlier is alive and well in Mexico.

Baretta tries to nail a seemingly untouchable crime czar by placing the aging man under painfully overt 24 hour/day surveillance.

Baretta's career and reputation are almost ruined by a beautiful photographer who tricks him into helping her steal a half million dollars of mob money.
