Wealthy, handsome, charismatic Cas Finley is restless. He likes women, too much, perhaps, as he seeks variety, and has been with Alice for longer than usual. Now finding her too bland and smooth, too elegant to make a farmer's wife, and incidentally afraid of llamas, his latest venture, he is wondering how to drop her without giving pain.
Lucy, widowed when her unsatisfactory pop star husband is killed in a car accident, moves to Shorter's Green on the edge of the Chilterns to find a new life. She intends to start a mobile hairdressing salon. She is off men, except perhaps for Edward, a staid widower she's known since childhood, who is restful after the pop star life.
Recalling her encounter with a gorgeous man that morning, Lucy is drowning her sorrows after Edward breaks a date, when she is visited by Rosa, the llama, invading her kitchen. Almost against her will she becomes involved in Rosa's love life as Cas seeks a mate for her.
