Years ago, Devan, a member of the Maanikesseri royal family, fell in love with Ganga, a 'dasi' (servant) girl.

Enraged, Thampuran slaps and beats Ganga and his goons throw Devan inside a room and lock him.

Fearing her wrath, the Maanikesseri family members hire an exorcist, Mepaddan, who successfully gets hold of the spirit and imprisons her in a Banyan tree.

But trouble starts brewing when Unnikuttan, befriends and falls in love with Maya, a girl whom he met on the sets of a movie shoot.

Things go haywire; Maya begins attacking family members who suspect her identity, seducing Unni and becomes pregnant.

Meppaddan reveals the reason; Daisy is actually a college girl hailing from a Christian background.

Meppaddan also reveals that since Ganga has now become powerful, it would be difficult to exorcise her and that she would either take the life of any of the family members or else would kill her host Daisy.

The fiery exorcism takes place with Meppadan battling the stubborn Ganga, who wouldn't leave Daisy until she fulfils her wishes.
