Summary

Dateline investigates the 2020 disappearance of Talena Galloway, a widow from rural Oklahoma who vanished after posting ominous Facebook messages about her illness. Amateur sleuths known as "Talena's Army" uncover her secret involvement in the Gorean subculture and financial ties to a former master, Marty. Suspicion shifts to her roommate, Corey, who sold Talena’s belongings and has a history of fraud, while her ex-husband warns investigators to look for poisoning with ricin.
