It's 1967 and the era of free love, drug experimentation and the Vietnam War is in full effect. When the teenage daughter of a respected lawyer goes missing, L.A. Police Sgt. Sam Hodiak (David Duchovny, "Californication," "The X-Files") starts asking around. He soon discovers that the hippie kids he's questioning don't take kindly to cops, especially one with hair as short as his. Needing the help of someone they will trust, he partners with rebellious undercover cop Brian Shafe, a man who's more comfortable rolling a joint than patrolling a beat. It's not long before they stumble upon a small-time cult leader seeking out vulnerable women to join his cause. From there, they follow this man's trail down a rabbit hole of drugs, sex, murder and cultural revolution. Little could they know, however, the guy they're hunting will eventually become the killer we now recognize as Charles Manson. He was a lost soul who desperately wanted to get into the music scene of the '60s until something snapped. This is the show that will explore the cat and mouse game between him and the police that will go on for several seasons, ultimately ending with the infamous Tate-LaBianca murders.
