A newly "retired" Hodiak (David Duchovny) tracks down the serial killer who has been tormenting him for months, without the protection and authority of his police position. Manson (Gethin Anthony) sends Tex (Cameron Deane Stewart), Sadie (Ambyr Childers), Emma (Emma Dumont) and Patty (Madisen Beaty) to 10050 Cielo Drive, where they are swept up in one of the most infamous crimes in the country's history.
