Emma Porter has just been dumped by her longtime beau for a glamorous younger woman. Rather than cancel their planned trip to view the gardens of England, she decides to make the journey solo. An avid gardener herself, she feels this is just the balm her troubled ego needs. She gets far more than she bargained for when a pair of elderly sisters send her to view fabulous gardens owned by a Duke.
Before she has barely set foot on the soil, she finds herself designing the Duke's chapel gardens, preparing for a once-a-century fete, reconnecting a handsome handyman with his two young children, solving the murder of a rock star, and leading the Duke to wed the woman he has desired for years. Meanwhile, Aunt Dimity keeps her finger in the pie and all live happily ever after.
