On July 4, 1969, the infamous Zodiac killer attacks a couple, Darlene Ferrin (Ciara Hughes) and Mike Mageau (Lee Norris), at a lovers’ lane in Vallejo, California. Mageau survives while Ferrin dies from her injuries.
One month later, a letter written by the Zodiac arrives at the San Francisco Chronicle. Paul Avery (Robert Downey, Jr.) is a Chronicle crime reporter. Robert Graysmith (Jake Gyllenhaal) is a political cartoonist there. The newspaper receives encrypted letters that the killer sends, taunting the police. Because of Graysmith’s status as a cartoonist, he is not taken seriously by Avery and the editors and is excluded from the initial details about the killings despite his interest in the case.
In particular, he is drawn to the encrypted code that is included with the letters and is given access to one. When he is able to crack one of the codes and makes several correct guesses about the killer’s actions, Avery begins sharing information with him. While at a bar together drinking Aqua Velvas, which Avery initially makes fun of Graysmith for, they discuss the coded letters. Wikipedia
