Based on the Novel “Secretariat: The Making of a Champion” By William Nack, Secretariat chronicles the spectacular journey of the 1973 Triple Crown winner. Housewife and mother Penny Chenery (Diane Lane) agrees to take over her ailing father’s Virginia-based Meadow Stables, despite her lack of horse-racing knowledge. Against all odds, Chenery-with the help of veteran trainer Lucien Laurin (John Malkovich)-manages to navigate the male-dominated business, ultimately fostering the first Triple Crown winner in 25 years and what may be the greatest racehorse of all time.
