Agnisakshi is a devotional drama that shows the struggle of a simple village girl Shibani (Soumili Biswas). Satya Narayan Chowdhury (Soumitra Chatterjee) is highly impressed with Shibani and gets his son Surya married to her. But Surya makes it clear that he is not interested in the marriage at all. Now Shibani's only hope is Lord Shiva. Will the almighty Shiva be able to unite the couple?
