Debasree Roy is all set to make her OTT debut with the Hoichoi series Chemistry Mashi in which she plays Sucharita Lahiri, a woman in her late 50s, who finds herself at a crossroads in life. Despite being in a marriage to a bureaucrat for 30 years and raising successful children, a conflict within her family prompts her to question her own identity and dignity. Deciding to carve her own path, Sucharita revives her passion for chemistry through an engaging online channel, "Chemistry Mashi", where she teaches in a unique and relatable manner.

Her popularity increases to such a level that she starts teaching students for entrance examinations. However, her popularity takes a dark turn when one of her suggested question papers coincidentally matches an exam, triggering accusations of a question paper leak. As the series progresses, her family equations also keep changing.

Directed by Sourav Chakraborty, Chemistry Mashi becomes a narrative of resilience, integrity, and the fight against corruption as Sucharita stands up against powerful forces to prove her innocence and unveil a systemic conspiracy.

“Honestly, I'm feeling a mix of excitement and tension because, up until now, my professional background has been in the realm of movies. Venturing into the OTT space is a completely new experience for me. However, I've been patiently waiting for the right opportunity to make my OTT debut, and when Sourav and Hoichoi presented the script for Chemistry Mashi, I was captivated. There was no turning back for me because the script is truly exceptional, and I genuinely wanted to be a part of it," said Debasree.

Shankar Chakraborty plays Sushavan Lahiri, Sucharita's husband. "Chemistry Mashi in essence narrates the collective story of mothers who have devoted their lives to household duties, particularly those spent tirelessly in the kitchen. Sucharita Lahiri, portrayed by the talented Debasree Roy, epitomises one such mother. One day, she resolves to break away from the routine she has followed for the past 30 years. However, this decision triggers significant changes and presents numerous challenges in her life. This is the central theme explored in Chemistry Mashi. Reflecting on my filming experience, collaborating with Debasree Roy has been nothing short of a lifetime journey, and Hoichoi has evolved into a comforting home for me. Returning to it always brings a sense of warmth and familiarity," said Sourav.
