Mark Ruffalo

A powerful, true story about members of the Navajo tribe who proudly served the U.S. in WW II as code talkers by using their native language as a code to relay information to military leaders. Unbeknownst to the Navajo is the dark secret that they're to be killed by American soldiers if one of them is in danger of being captured.

Based on the Robert Graysmith books about the real life notorious Zodiac, a serial killer who terrorized San Francisco with a string of seemingly random murders during the 1960's and 1970's.
