Newly appointed art curator Molly Goode is committed to diversifying her museum’s collection. When Georgina Wright, the museum’s aloof benefactor, asks for Molly’s help in identifying the provenance of a 19th century portrait of social activist Josephine Brancaster, Molly welcomes the opportunity, even if it means spending time with the standoffish financier. But passions soon flare as the women uncover the heartbreaking story of doomed lesbian love behind the watercolor painted by Josephine’s lover, Edith Hewitt.

As their love blossoms, Molly is determined to display Edith’s portrait of Josephine and to tell their story in the museum, but she needs the influential Georgina to help convince the board. When an unforeseen twist in the painting’s provenance forces Georgina to confront her own painful past, will history repeat itself, or can Molly and Georgina’s love prevail?
