Seaside, England, 1886. Eva Caldwell is an accomplished photographer who often works to assist in documenting crime scenes, which means she also works alongside the charming Detective Nathan Winston. One evening, Nathan arrives on her doorstep asking for a favor. Would Eva be available to photograph his mother's week-long dinner party and matchmaking event? Sounds simple enough. But when a criminal from Nathan's past threatens revenge on the detective, Nathan must be extra vigilant. He confides in Eva, and as the two work together to solve the mystery and apprehend the criminal, they find that they might capture more than they expected - each other's heart.
