The village has just buried all the memories of the staggering Northern war. He (Sunimal) finds shelter in the house of chieftain of the village 'Ralahami mama' who does not bother about his past, but his present. Sunimal, while trying hard to get over his indelible memories of war, faces his second battle of life as he can't resist the charm of Yasho, Ralahami mama's daughter. When he loses his battle, the dark shadows of an unforeseen future surrounds him....again. Yet he must discover himself, his real family, and his future.
