Zodiac (2007)

In the late 1960s/early 1970s, a San Francisco cartoonist becomes an amateur detective obsessed with tracking down the Zodiac Killer, an unidentified individual who terrorizes Northern California with a killing spree. The true story behind the murders that many crime scholars believe to be the most perplexing series of unsolved crimes in modern history comes to the screen in chilling detail as Fight Club and Seven director David Fincher steps behind the camera to tell the mysterious tale of the infamous Zodiac killer. A relentless serial killer is stalking the streets of the San Francisco Bay Area, leaving citizens locked into a constant state of panic and baffled authorities scrambling for clues. Though the killer sadistically mocks the detectives by leaving a series of perplexing ciphers and menacing letters at the crime scenes, the investigation quickly flat-lines when none of the evidence yields any solid leads. As two detectives remain steadfast in their devotion to bringing the elusive killer to justice, they soon find that the madman has control not only over their careers, but their very lives as well. Based on real events, this chilling drama recounts the actions of a killer who stalked the streets of San Francisco and left clues in the newspaper.
