SUPER 30 is the story of a selfless man fighting for the cause of education-for-all. The year is 1996. Anand Kumar (Hrithik Roshan) has completed his graduation and is passionate about mathematics. He's so good in the subject that he is felicitated at the hands of the education minister (Pankaj Tripathi). Anand manages to solve a complex mathematical problem, which has baffled scholars all around the world. His feat lands him a seat in the prestigious Cambridge University. His father Eshwar Kumar (Virendra Saxena) is a postman who takes out his PF to fund Anand's foreign education.
When the money falls short, he and Anand knock at the doors of the education minister, who had promised him help. But the minister refuses to help. Meanwhile, Eshwar passes away one day suddenly. He was the only earning member of the family and hence, Anand sheds his ambition and begins selling papad to survive. One day, he bumps into Lallan Singh (Aditya Srivastava) who runs Excellence Coaching Centre, an institute for those giving the IIT-JEE exams. He is aware of Anand's brilliance in mathematics since he was in the college when Anand was felicitated. He gets Anand enrolled in his coaching institute as a premium teacher. Since Anand's teaching methods guarantee success, he becomes quite sought after. Excellence Coaching Centre management even promote themselves by using Anand's picture on their banners.
Anand's financial condition also improves as he's even made one of the signatories. However, he soon realizes that some brilliant students aren't getting a fair chance to excel in life because of their underprivileged background.
Overnight, Anand quits Excellence Coaching Centre. He starts his own centre, where he decides to teach 30 students for IIT entrance exams for free. Not just that, he even arranges for their accommodation and food. Lallan obviously is livid and he tries his best to persuade Anand. When nothing works, he tries to demotivate Anand, saying that all his students who fail will go back to their impoverished lives. It's important that each and every student of Anand manages to crack the IIT exam. What happens next forms the rest of the film.
