On Becoming a God in Central Florida follows Krystal Stubbs, a minimum-wage water park employee who lies, schemes and cons her way up the ranks of Founders American Merchandise (FAM) — the cultish, flag-waving, multibillion-dollar pyramid scheme that drove her to ruin in the first place, run by the powerful Obie Garbeau II. Determined to make a better life for herself, Krystal dives deep into FAM and develops a tangled relationship with FAM's most loyal and fanatical follower Cody, until her business begins to affect those closest to her, including Ernie, her affable water park boss, and his FAM-skeptic wife Bets.
