MAGNUM FORCE (1973)

Rogue San Francisco cop "Dirty Harry" Callahan (Clint Eastwood) doesn't believe in blind obedience to the rules, but when a vigilante group starts executing criminals who have escaped punishment on technicalities, that's going too far. Against the orders of his commanding officer, Lt. Briggs (Hal Holbrook), Callahan begins investigating his hunch that another policeman is behind the killings - with the primary suspect being his tightly wound ex-partner, Charlie McCoy (Mitchell Ryan). Director: Ted Post. Cast: Clint Eastwood, Hal Holbrook, Mitchell Ryan, David Soul, Felton Perry and Robert Urich.
