Oona Kelly Webster is an editor at a New York publishing house. Married with two children, her twenty-five-year relationship falls apart when she books a silver wedding anniversary getaway at a luxurious chateau in France and her husband Charles suddenly refuses to attend. What he tells her next will shatter her carefully built world into smithereens. As her two children, Meghan and Will, rally around her in New York, one disaster heralds another: Oona can't back out of her French holiday booking and must travel to a new country with a heavy heart. It is February 2020 when she arrives and when France locks down due to the pandemic, Oona must stay put in rural, wooded Milly-la-Fort just outside Paris. And when a chance encounter with a famous Hollywood actor, who is renting a neighbouring chateau, blossoms into something deeper than friendship, Oona learns that life can change in an instant.
