She, then featured in Nirmal Sarbanga's road film "G. T. Road" (1980). The film did not perform well at box office. During this time Tarun Majumdar came up with the offer for his romantic drama film "Dadar Kirti" (1980) and suggested to change her name into "Debashree Roy". Her mother never objected to it. She was cast alongside Sandhya Roy, Kali Banerjee, Ruma Guha Thakurta, Tapas Paul and Mahua Roychoudhury in the film. She portrayed the character of Bini, the innocent sibling of Saraswati portrayed by Mahua Roychoudhury. The film became a remarkable box office success and her role and vibrant appearance was loved by the audience, alongside the reverse and solemn appearance of Mahua Roychoudhury.
