1901, Wiltshire. Young Kathleen Keller is being forced into marriage with a man she despises by her cruel father. In an act of desperation, she runs away in a bid for a safer life, although one she might not have otherwise have chosen. But when tragedy strikes, Kathleen is left vulnerable and one man threatens the fragile peace she has made for herself.

Meanwhile, Nathan Perry works for his father's accountancy firm but yearns for something more satisfying. He is brought in to help with the purchase of Honeyfield House, intended as a safe house for women in trouble by a charitable benefactor, and there encounters Kathleen. Their lives are set to intertwine and neither will be the same again.
