Sony LIV’s upcoming series, 13th: Some Lessons Aren’t Taught in Classrooms will be released on the platform on October 1, the makers announced on Friday. It is inspired by the life and philosophy of Mohit Tyagi, visionary mathematics teacher and founder of the education startup Competishun. The show is created and written by Sameer Mishra and directed by Nishil Sheth and stars Paresh Pahuja, Girija Oak Godbole, Pradnya Motghare, Abhishek Ranjan, Keshav Mehta, Jai Kishan, Ashish Raghav, Ajay Chakraborty and Rajendra Bhatia in pivotal roles.

Its trailer was unveiled by the makers on Friday. It follows the journey of Ritesh (Paresh), a rising venture capitalist who gives up everything to repay a debt not written in numbers, but in belief. The trailer opens with a rousing monologue that Ritesh gives in the middle of a meeting as he later goes on to quit his job. Years ago, it was MT Sir (played by Gagan Dev Riar), his mentor, who shaped his path. Now, as life comes full circle, Ritesh steps away from the boardroom to stand by his teacher and help him build a bold new ed-tech dream.

Talking about the series, Paresh, who plays Ritesh, said in a statement, "This show is a simple and honest portrayal of the influence and impact some mentors have on our lives. Ritesh, the character I play, is a brilliant student, but there comes a time when he realizes that even he needs help, and that's when Gaganji's character, MT Sir, comes into his life. I truly believe that we all have that one mentor who has brought out the best in us, and they need to be celebrated."

Produced under the banner About Films, the producer and showrunner of the series is Abhishek Dhandharia.
