The story follows Tashi, a tennis player-turned-coach who has taken her husband, Art, and transformed him from a mediocre player into a world-famous Grand Slam champion. To jolt him out of his recent losing streak, she makes him play a "Challenger" event -- close to the lowest level of tournament on the pro tour -- where he finds himself standing across the net from the once-promising, now burnt-out Patrick: his former best friend and Tashi's former boyfriend.
