England, 1940. The world's last copy of the Middlebury pink camellia grows on the territory of the country estate. On the eve of the Second World War, the American Flora makes a deal with a thief. Her task is to infiltrate the estate and find the camellia. The path to this goal turns out to be filled with joy and fear at the same time... New York, our time. Addison, who works as a landscape designer, comes to the same estate with her husband Rex. This house is now owned by Rex's parents. He, like his wife, adores detective stories, so the couple, having found an album with dried camellia flowers in an old house, decides to investigate. And what if the danger that Flora once faced has not yet passed? Will Addison suffer the same fate as that girl?
