Collection of three popular cop movies. In 'Nico' (1988), Steven Seagal stars as Nico Toscani, a martial arts detective who discovers that a group of drug barons are about to bring chaos to the streets of Chicago. With the help of his partner (Pam Grier) he soon discovers that the drugs cartel is run by Zagon (Henry Silva), a CIA official with whom Nico had worked during the Vietnam war. In classic action movie 'Bullitt' (1968), Steve McQueen stars as Frank Bullitt, a San Francisco detective who has become hardened to crime. He is assigned by an over ambitious politician Chalmers (Robert Vaughn) to protect a key Mafia member who is due to appear in hearings that would catapault Chalmers into the public eye. But the safe house is ambushed, his friend is murdered and the witness is critically injured. Bullitt decides to search for the origin of the leak and the killers himself, despite Chalmers trying to interfere and shut down the investigation in a bid to keeping the hearings going. Finally, 'Dirty Harry' (1971) is the first in a series of films featuring Lieutenant Harry Callahan (Clint Eastwood) - a right wing, bad-tempered San Francisco policeman, not averse to bending the rules to get his man. The maniacal 'Scorpio Killer' is on the loose and Callahan disregards procedure in his efforts to track him down, using his trusty Magnum .44 to dispense his own brand of justice.
