The life story of Penny Chenery, owner of 1973 Triple Crown winner Secretariat. Chenery was a mother and housewife who knew little about horses when she was pressed to take over her ailing father's horse farm in Virginia. Though Secretariat came along and began to take shape as a potential champion, Chenery was pressured to sell the farm after her father died and she was hit with a multimillion-dollar inheritance tax.
