From cultish to adultish.
After getting accepted to Brooklyn College, Leah Masters convinces her cult leader parents, Rainey and Connor, to allow her to leave "The Mountain" with the promise that she will vigorously recruit new "Mountaineers". However, unbeknownst to her parents, Leah is joined by ousted cult member Clarissa Duffer whose true reason for her banishment remains a secret to Leah.
Clarissa leads Leah on the adventure of her life, introducing her to makeovers, hooking up and the college social scene.
As Leah adapts to life outside the commune, Connor and Rainey fight to secure the survival of "The Mountain". What they don’t know: they and "The Mountain" are under surveillance by the FBI.
