The film begins with Senna's arrival into Formula One during the 1984 season, briefly covering his time at Toleman and Lotus before concentrating on his time with the British team McLaren – the association that brought his rise to global fame – and becoming a World Champion. The drama of this period of his career centers on his rivalry with his team mate Alain Prost, and his political struggles with the then head of FISAJean-Marie Balestre, climaxing during the 1989 and 1990 seasons, when Senna and Prost were involved in controversial clashes which decided the drivers' world championship title, in 1989 for Prost and in 1990 for Senna. The film portrays the increasingly complex dynamics and tumult that characterized Senna's years as world champion, his battle to improve his sport's safety, and his reactions as he witnesses accidents and eventually the death of Austrian fellow-driver Roland Ratzenbergerthe day before his own. We see and hear through Senna's point of view that innovative computerization led in these years to the technological domination of the Williams cars, with Prost joining Williams and, in a fallout with Senna, refusing to be on a team with Senna anymore. The documentary reaches its finale as Prost retires and Senna takes up a champion driver spot with Williams, the Grove-based team in 1994, just as Formula One rules change, disallowing computerization, and the Williams' cars undergo rapid reconfiguration that proves fatal. In the culminating weekend of his life, at that year's San Marino Grand Prix, footage shows Senna under extreme stress, troubled as safety conditions reveal their weaknesses in one track accident after another over three consecutive days. Rubens Barrichello is injured in a crash during Friday qualifying, Ratzenberger is killed in an accident during final qualifying on 30 April, and at the start of the race JJ Lehto stalls and is hit at high speed by Pedro Lamy. The safety car is brought out, and when racing resumes, Senna crashes fatally on lap 7. The film concludes with the Senna family and his close friends from Formula One mourning his loss at his funeral.

Reception
Critical response
Senna received critical acclaim from critics. The film has a 92% "certified fresh" rating and an average rating of 7.9/10 on the review aggregator website Rotten Tomatoes, based on 116 reviews, with the consensus: "Even for filmgoers who aren't racing fans, Senna offers heart-pounding thrills -- and heartbreaking emotion." Dan Jolin of Empire Magazine gave the film 4 stars out of 5 and stated that it is "ambitiously constructed, deeply compelling, thrilling and in no way only for those who like watching cars drive in circles". Steve Rose, writing in The Guardian, also gave the film a 4 out of 5, and praised the fact that "with so much recorded footage of Formula One available, it has been possible to fashion Senna's story as a live action drama rather than a posthumous documentary. We're not so much hearing what happened in the past as seeing it happen before our eyes." Alain Prost was highly critical of the film and its depiction of his relationship with Senna as he felt it did not adequately explore the way their relationship changed from rivals to friends in the final months of Senna's life.
