In the fog-shrouded streets of late 1960s San Francisco, a serial killer known as the Zodiac begins a terrifying game of cat and mouse with the public and the press. Directed with meticulous precision by David Fincher, this gripping drama-thriller chronicles the obsessive hunt for the elusive murderer who taunts authorities with cryptic ciphers and letters. The investigation consumes the lives of three men: dogged homicide inspector Mark Ruffalo, flamboyant and brilliant crime reporter Robert Downey Jr., and the increasingly obsessed cartoonist Jake Gyllenhaal, whose fascination with the case becomes an all-consuming quest for the truth. As years turn into decades, the shadow of the Zodiac looms large, blurring the lines between professional duty and personal ruin in a chilling examination of obsession, where the pursuit of a name becomes more haunting than the crimes themselves.
