The author of the series, Tenkasi Balakumaran (Jayaram), leaves his home for a few days to be alone to write the final few episodes of Manga. On his way back home after completing his work, his vehicle gets into an accident which leaves him seriously injured and crippled.

Julie asks Bala to allow her to read the scripts for the concluding episodes that he has just completed.
Over the next few days, she reads the story and finds the ending not to her liking. She forces Bala to rewrite the ending by various means, forcing him to escape his captor's clutches before it is too late. Soon after, Bala becomes aware of how Julie has not informed anyone of his situation and is not at all planning to release him anytime soon. As a result, he tries to escape her home.
