This is: Incident at Our Lady of Perpetual Help:
The play tells the story of the O’Sheas, a cash-challenged, Irish-Catholic family just trying to get through 1973. Linda O’Shea, our 19-year old narrator, is attempting to re-enact for the audience the most turbulent day of her life, but her family keeps interrupting, insisting on telling their side of the story. The 1970s was a time of old-school living. No Facebook, no tweets, no texting, no Skype. A time when public ridicule in a close-knit, hermetically sealed Catholic parish was the ultimate nightmare. When Linda’s mother leaves it to Linda to tell her younger sister about the birds and the bees, the bawdy conversation is somehow overheard by the parish priest…and Father Lovett is not amused. He sets out to confront the family about “the corruption of their eldest daughter’s soul.”
