In the early 1980s, after giving up a career as a lawyer, Pierre Durand devotes himself to his passion, horses and show jumping. Having won several competitions with the support of his father, he dedicates himself to Jappeloup, a young horse purchased from a neighbor. Although no one else has confidence in this temperamental and unpredictable horse, Pierre sees its remarkable abilities and, together, they become a team. From one competition to the other, the duo takes the world of horse-riding by storm, up until their bid for a medal at the 1984 Olympics in Los Angeles, which ends in failure. But with the help of Nadia, his wife, and Raphaëlle, the horse's groom, Pierre succeeds in leading Jappeloup to the Seoul Olympics of 1988.
