The story begins with a news item of the demolition of the Daffodils, an erstwhile cultural hub where creative people met and discussed their work. The most prominent among them was filmmaker Siddharthan (Mohanlal), fondly called Sidhan, which can loosely be explained as a genius. He used to develop his scripts there and would meet his Thadi-Jubba-Sanji kind of friends here for drinks and other pleasures. Sidhan had mysteriously died by falling from the terrace of the building. It was not proved whether it was an accident, suicide or a murder.
So, his foster son Adi (Anup Kumar), himself a renowned writer, whose previous book Labyrinths of Sanity (for pun's sake, it should have been Labyrinths of Insanity!) was short listed for Man Booker Prize, embarks on a mission to write a biographical novel. In fact it is about Siddharathan's relationship with various women as Siddharathan is a womaniser. Womanising is presented as a "mystical quality in a creative genius about his father in addition to solving the mystery behind his death.
He completes the book in two weeks flat and requests his wife (played by Lakshami Gopalaswamy) to appraise it as a reader and a critic. The narrative unfolds in anecdotal flashbacks as the writer and his wife discuss the book. The string of people he meets, his father's friends, his colleagues, the suspects and even the police officer who had investigated the case.
