Barobabu is inspired by the life and work of Shishirkumar Bhaduri, the towering figure of Bengali theatre. Rather than a chronological biopic, the film delves into his emotional world — a complex weave of love, art, and personal turmoil. It explores his deep connections with two actresses, Prabha Debi and Kankabati, both significant in his professional and personal life.
