After marriage, Sita discovers that her sleepwalking is not the usual kind, as it takes her to the story of her past life. Chitrasen, an artisan, was in love with the princess Neel Kamal (Sita in her past life). The king  rejects his alliance for his daughter and as a punishment, buries him alive. Chitrasen's love for Neel Kamal remained immortal and his soul survives for centuries in hopes to meet her and be with her. One night, while sleep walking, Sita is invited to Chitrasen's burial by a song. Her mother-in-law, a very cross person, believes that Sita is having an affair and gives her a tough time at home along with her sister-in-law Chanchal.
