Konkona, who also features in the Kannan Iyer's directorial debut, does a cameo in the episode, which will go on air Saturday and Sunday. She plays herself in it.
Based in Kolkata, the story is about a middle-age theatre veteran Tanushree Dasgupta, played by Mouli. She is paying a tribute to her mentor and one time leading actress Uma Biswas by doing a play in her honour.
During the staging of the play she meets a newcomer called Laboni, who gives a fantastic performance in the play.
But Tanushree realises unusual things happen when Laboni is around.
Then enters Konkona, who helps Tanushree find out the real picture.
Ekta and co-producer of the film Vishal Bhardwaj will also be seen doing cameos in "Ek Thhi Naayka".
