In 1967, Los Angeles police sergeant Sam Hodiak, who goes undercover to track Charles Manson and the Manson Family before their infamous murder spree, is helped in a missing persons case by undercover officer Brian Shafe, who behaves like a hippie and fits in with the people being questioned. Unbeknownst to them, their investigation will lead them to Charles Manson.
Every time the show looks like it might wade into ambiguous territory, it snaps back to that dull morality: Manson is a bad man, Hodiak the hero who must hunt him down. It's hard to disagree, but it's also hard to really care.
How much of this is based on "fact" and how much is based on baloney? Never explained, but there appears to be enough of the latter to make a generous sandwich.
