Emma Dumont (“Bunheads”) is set to star in NBC’s new 13-episode event series “Aquarius.” The show follows a Los Angeles police sergeant (David Duchovny) in the 1960’s investigating a young hooligan and charismatic cult leader named… Charles Manson (Gethin Anthony).

Dumont plays young Emma Karn, one of Manson’s recruits whose father is embroiled in the cult leader’s “far-reaching conspiracy.” Dumont is best known for playing Melanie Segal on ABC Family’s short-lived dramedy series “BunHeads.”

“Aquarius” is written by John McNamara (In Plain Sight) and executive produced by Duchovny.
