Remember in kindergarten when the true and kind teacher stood in front of the blackboard and explained to all her young charges that the police were honest, good, and brave men who protected well-behaved boys and girls from predatory drug addicts and hostile sex maniacs? Plan to forget all that before venturing into the evil, slick, and spun plot twists of Internal Affairs (1990). Dark and intense Andy Garcia stars as a cop whose job is to investigate other cops. Not only does proof exist that rotten apples on the force are committing larceny and even murder, but evidence shows that one of the bad guys might be bedding Andy’s wife. Job stress is a killer.
