Shows like Fatal Vision

In 1970, military doctor Jeffrey MacDonald reports a hideous and confusing story: a gang of hippies akin to the Manson Family broke into his North Carolina home and slaughtered his pregnant wife and two daughters, while somehow only wounding him slightly as he tried to fight them off. As he continues to proclaim his innocence, his skeptical father-in-law, Freddy Kassab, and investigative journalist, Joe McGinniss, probe his story to uncover the truth.
