It's October 1970 in Montreal, Quebec. Nadine is a trade unionist with the garment-workers union. Twenty years earlier in 1950, at the age of 15, she was banished to a home for unwed mothers. Her baby daughter, whose father is shrouded in secrecy, was given away for adoption without her permission. This prompts her to cut all ties with her mixed Irish and French-Canadian Catholic family whose past is cluttered with secrets, betrayals, incest and violence. She vows to one day she will reunite with her daughter.

Following the FLQ kidnapping of a British Trade Commissioner and the Quebec Minister of Labour, Ottawa proclaims the War Measures Act and sends the army into Quebec. These staggering political events spark an unexpected encounter between Nadine and one of her estranged grandfathers from Quebec City, thus opening the door to contacting the family. It also lays the foundation for a reunion between Nadine and her daughter Lisette, embittered after been bounced from one foster home to another since she was a baby. Lisette and her partner Serge, who is close to the FLQ, need money and see Nadine as a possible source based on information they've gathered about Nadine's family.

World Wars I and II, the Great Depression, and the 1970 October crisis provide the backdrop to this family saga spanning some 60 years. Murielle Cyr breaks new ground by telling The Daughters' Story, an unsung, overlooked but intensely passionate tale of women, propelled by their unquenchable need to belong despite oppressive conditions hard to imagine nowadays, and who manage to survive and thrive.
