The film starts in the 1960 Summer Olympics in Rome, in which Milkha Singh (Farhan Akhtar) is competing in the 400-metre. A coach yells "Bhaag Milkha Bhaag!" ('Run, Milkha, run!'), and Singh is suddenly taken back to the memories of his childhood which haunt him, resulting in him dropping to fourth place. His memories are of the chaos surrounding the 1947 Partition of India, which resulted in mass religious violence in Punjab and the killing of Singh's parents. The flashback shows Singh reaching Delhi alone, where he later meets his sister. Living in impoverished refugee camps, Milkha makes friends and survives by stealing with them. Now grown up, he falls in love with Biro (Sonam Kapoor), who asks him to live a life of honesty. Milkha soon finds himself in the army. There, he wins a race in which the top 10 runners are rewarded milk, two eggs, and are excused from fatigue duty; his running skills are noticed by a havaldar (sergeant). He gets selected for service commission, where he is miffed. On the day before selection of the Indian team for the Olympics, Singh is beaten up by senior players whom he had defeated earlier. Despite being injured, he participates in the race and overcomes his pain: he wins the race and breaks the national record. Proud of his achievement, Milkha goes back to Delhi to ask Biro's hand in marriage. However, his friend informs him that Biro was married and left Delhi. During the Melbourne 1956 Olympics, Singh is attracted to Stella (Rebecca Breeds), the granddaughter of his Australian technical coach. After a frolicking night in a bar, they have a one-night stand. The following day, he feels exhausted from the night's activities and loses the final race. He realises his mistake and, suffering from guilt, he even slaps himself in front of a mirror. On the flight back to India, he asks his coach what the world record is for the 400m race and learns that it is 45.9 seconds. A montage of tyre training in the cold desert of the Himalayas is depicted, wherein Milkha Singh pushes himself to the brink of absolute exhaustion. He subsequently enters the 1958 Asian Games with the hope of winning Gold for India. He then sees Abdul Khaliq (Dev Gill), dubbed the "Fastest Man of Asia". After Abdul wins his race, Milkha Singh approaches him to congratulate the victor. However, the Pakistani coach and his athlete shun him down by disrespecting him. He finally gets his revenge in the 200m where he defeats Khaliq by a considerable margin. Moving to the Commonwealth Games, he wins another Gold in the 400m and is named "The king of England" by various newspapers. After celebrating his victory along with his teammates in the Army, he burns the paper on which the time of 45.9 seconds was written, indicating that he was ready to break the world record of 400m. He finally achieves his life-long dream by breaking the 400m world record. Invited by the prime minister of India, Jawaharlal Nehru (Dalip Tahil), to lead the Indian team in Pakistan for a friendly race with Abdul Khaliq, Singh adamantly refuses to go due to the trauma of having to flee his home in the newly-formed Pakistan as a child. The prime minister comes to know of Singh's opposition but ultimately convinces him to go. Arriving in Pakistan, Singh misses the press conference and goes to his village where, in a flashback, it is shown how his parents were murdered and the last words of his father were "Bhaag Milkha Bhaag!" He starts crying and is comforted by a boy who turns out to be the son of his childhood friend, Sampreet; he then meets Sampreet, who evidently survived the chaos of partition. In the games, initially, Khaliq is winning, but Singh takes the lead after overtaking opponents one by one. Impressed how easily Singh passed the Pakistani athlete and won by a humongous margin, the president of Pakistan, General Ayub Khan, gives him the title of "The Flying Sikh." Jawaharlal Nehru declares a day in the name of Milkha as a national holiday as requested by Singh himself. A final sequence of Milkha Singh is depicted where he is enjoying his victory lap and everybody in the stadium is in awe of what he has achieved. He sees his younger self running beside him, as the film comes to a close.
