In October 2010, hunter Justin Smeja claims he shot two unidentified animals in California's Sierra National Forest, seven feet tall, walking upright like men. This film picks up where his earlier online video "I Killed Bigfoot" left off, following director Ro Sahebi as he re-interviews Smeja, tracks down the second hunter known only as "The Driver," and pushes Smeja through a formal polygraph exam, footage first shown in Sahebi's short "The Examination." Locals and researchers from the sasquatch community, including figures tied to the Sierras Evidence Initiative, weigh in on photographs, footprints, and trace evidence gathered from the shooting site. A staged nighttime recreation at the original location produces an incident the crew did not expect, which the film presents without resolving. Sahebi keeps the camera on Smeja's inconsistencies and his defenders in equal measure, treating the case less as proof of a creature than as a study of how a single disputed claim, later dubbed "The Sierra Kills," hardened into legend inside a specific subculture.
