The Mulvaneys, a family living in the small, rural town of Mt. Ephraim, New York, during the later part of the 20th century, are the perfect family: four kids, the owners of a successful roofing business, and a high social status. We Were the Mulvaneys tells the tale of the demise of this perfect family-an incident that is hushed up in town and never spoken of again. It is this incident that shatters the family fabric with tragic consequences.
