A parole officer is murdered after telling Baretta that a model who supposedy killed herself months earlier is alive in Mexico.

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

After Baretta kills a drug pusher in a shootout, the man's teenage brother vows revenge.

Baretta comes to believe that a mobster is being framed for the murder of his boss when the man's girlfriend is too scared to confirm his alibi.

When his partner is charged with shooting a suspect in the back, Baretta tries to locate the only witness who can save the man's career, but the real murderers are after him too.
