Visionary creator Luca Guadagnino presents Challengers with Zendaya in the role of Tashi Duncan, who, as the golden child of tennis, due to an injury, became an uncompromising coach... on and off the court. Her husband (Mike Faist - West Side Story) is a champion who is going through a professional crisis. Tashi decides to restore him to his former glory, but they are both in for a surprise when the opponent turns out to be another expired champion, Patrick (Josh O'Connor - The Crown) - his former best friend and Tashi's former boyfriend. When the past collides with the present and tensions run high, Tashi must ask herself what will be the price of this victory?
