This is Al Pacino at his best. As a New York City cop, he sees corruption all around him. When he refuses to extort money from criminals, his fellow officers turn against him. When he tries to do his job, he experiences vengeance in the worst form. A grand jury inquiry only makes things worse.
Based on a true story, Serpico helped to bring corruption into the headlines. The gritty realism of the film shows the versatile actor in a character that will stay with you long after the film ends.
