The upcoming Federer: Twelve Final Days documentary offers a rare glimpse into the last 12 days of Roger Federer’s career, revealing his heartfelt reflections on retirement and its impact on his family. The trailer is already out, and Vogue magazine has just teased some emotional moments. Get ready for tears, Fedal fans!

The arrival of Rafael Nadal 46 minutes into the film marks its movement into the final aria of Federer’s career. No other player challenged him as consistently, or for as long, as Nadal, and no other player became so close to him personally. The affection between the two is tangible throughout. (It was Nadal, alone among players, whom Federer told about his retirement 10 days before anybody else outside his family and management.) Federer calls Nadal’s ascendance in the game “a bit of a mind bender” that, at first, wasn’t entirely welcome: “I liked being at the top alone,” he adds. Nadal, in turn, simply says that “the most important player in my career…is leaving,” and it’s clear on his face and in his eyes that the notion of Federer’s absence has forced a kind of reckoning of his own.

Again, the tennis obsessives among us will never forget the images we saw from the Laver Cup at the O2—of Federer and Nadal struggling to contain their emotions, sitting next to one another on a bench at the side of the court, holding hands, lips quivering, tears streaming down their faces—and their emotional on-court farewell is the beating heart at the center of this film. But we also see what nobody outside of their circle has ever seen before: Federer walking back into the locker room after their final doubles match to find Nadal still sobbing, a towel hiding his face. The two share another embrace before Nadal wills himself into an emotional gearchange, shouting, “Okay, done!”
