The film is framed as a fictitious HBO Sports documentary incorporating BBC footage. It explores the backgrounds of the competitors Aaron Williams (Andy Samberg) and Charles Poole (Kit Harington), two professional tennis players who face off in what becomes the longest match in history.
Aaron Williams is considered “The Bad Boy of Tennis.” He is an American orphan who was found on the streets and adopted by Richard Williams, who raised Aaron with his daughters, Venus and Serena Williams. At the 1996 Wimbledon Finals, his serve hits a line judge, who has an immediate heart attack and dies. Williams falters and loses the championship. At the ceremony following the match, Williams pushes Prince Edward, the Duke of Kent (Howie Mandel), and disappears.
Charles Poole is a British child prodigy forced into a tennis career by his domineering mother (Mary Steenburgen), who threatens to disown him if he loses. He appears on a sports talk show hosted by Caspian Wint (Michael Sheen) as a 15 year old and is on track to become the youngest professional tennis player in history. He tells Wint that he idolizes Aaron Williams.
