America's most vicious serial killer, The Zodiac, terrorised San Francisco in the late 1960s. The Zodiac killed five men and women, then left bizarre ciphers as breadcrumbs.
Although studied by the most advanced criminal justice experts of the time, only 25% of his ciphers were ever decoded.
Now, Sal LaBarbera - the most successful homicide detective in LAPD history - will work with a crack code-breaking team to hunt down The Zodiac. The key: a groundbreaking new investigative technique called a Double Helix Investigation.
Working with UCLA master codebreaker Kevin Knight, they'll take a novel approach to catching The Zodiac.
