In 2009 Dam appeared in seven Bengali films, and came into focus with the success of Kaalbela (directed by Goutam Ghose). Based on a Bengali novel by Samaresh Majumdar, the film's background was the Naxalite movement of the 1980s. Dam played Madhabilata, the girlfriend of a young Naxalite leader, and her performance was praised. In its review, The Times of India appreciated: "Pauli, who plays Madhabilata with such integrity that the pain in her eyes and the romance in her voice charms viewers to believe that she has it in her to lend her face to everything that Madhabilita has epitomised". In an interview, Dam said the film was a "turning point" in her career: "Everybody needs a platform – Kalbela gave me the platform. I had to prove myself". Her other six films released that year were Hochchheta ki, directed by Basu Chatterjee; Jamai Raja, directed by Swapan Saha; Box No. 1313; Mallick Bari; Shob Charitro Kalponik, directed by Rituparno Ghosh and Tinmurti.
