How to Plan an Orgy in a Small Town is all about a set of friends who live in the scenic town of Beaver's Ridge--the epitome of powerful and wholesomeness family values. Their orderly life is disrupted by the homecoming of Cassie Cranston (Jewel Staite), whom they slut-shamed into leaving town when she was a teen. Presently a big-city sex writer, Cassie locates an opportunity to get revenge whenever they ask her if she'll help them plan a orgy, also returns home to handle an unwelcome reception by her friends.
