As she immerses herself in the charm of rural life, she quickly forms a bond with Violet MacDonald, the warm-hearted owner of the local post office. Carla also finds herself drawn to the village's charismatic police sergeant, Alec Macroy. However, her new beginning takes a dark turn when a local man, Jack Dawes, is brutally murdered, followed by a second tragic killing. With both cases closed due to insufficient evidence, Carla and Violet refuse to stand idly by; they take matters into their own hands to uncover the truth and bring the elusive killer to justice.
