The film is about a Californian sorority of a different kind, following Christine Meeusen, a corporate exec-turned-cannabis-farmer who found her calling in medicinal marijuana. It tells how Meeusen, betrayed by a husband after 17 years, fled penniless with her three young children and discovered the lucrative business of cannabis farming. She adopted the persona of a nun called Sister Kate and founded Sisters of the Valley, a business that makes and sells medicinal cannabis products.
