Young parents Dave and Rebecca are ready to reclaim their life after years of diapers and sleepless nights. However, things take an unexpected turn when Dave's parents show up unannounced and broke, leaving Dave with no choice but to open the door to the people who gave him everything. But these boomerang parents aren't great with boundaries, and the question of who's parenting whom quickly becomes blurred.
The series centers on a formerly filthy rich video store magnate Johnny Rose, his soap star wife Moira, and their two kids, über-hipster son David and socialite daughter Alexis, who suddenly find themselves broke. They are forced to live in Schitt's Creek, a small depressing town they once bought as a joke.
