Sixteen-year-old orphan Gwen Davies (Sian MacLean) was raised on her beloved grandfather's farm in Wales. Her cherished way of life is threatened after he dies in a tragic accident. First, the owner of the local country club pressures her to sell the farm. Then, her estranged uncle Alan (Daniel J. Travanti), who has not been home in twenty years, arrives from America and is named her guardian. Gwen is convinced Alan will agree to sell the farm, but she is not going to give up without a fight. As Christmas approaches, she is determined to race her magnificent stallion, Mabon, that was her grandfather's hope for the future. Meanwhile, Alan's emotional homecoming will force him to come to terms with his past.
