The film opens and closes with a tennis match. On one side of the net is Art Donaldson (Mike Faist), the face of Wilson tennis rackets, stopping by this second-tier challenger tournament for a confidence boost on his way to attempt a Grand Slam. On the other side of the net is Patrick Zweig (Josh O’Connor), a broke and low-ranked competitor, who sleeps in his car before using online dating to secure a bed during the tournament. After winning their respective brackets, Art and Patrick face off in the finals. Between the beginning and end of the match are a series of flashbacks that raise questions about what the men are competing for.
