In Netflix’s “Untamed,” Eric Bana plays a rugged, no-nonsense special agent for the National Parks Service working the mystery of a woman’s death in Yosemite.

Co-created by 'American Primeval' scribe Mark L. Smith, this six-episode thriller traces a murder investigation in the famous national park.

Onscreen, at least, there are enough rangers to keep Yosemite running and to investigate a mysterious death at El Capitan.
