The film captures the ascent of the protagonist, Shankaran Kutty, from a carefree individual to a mature responsible adult. The opening sequences shows Shankaran Kutty attending a temple festival. The film proceeds to show the irresponsible and often nomadic life style of Shankaran Kutty. Shankaran Kutty, though seemingly at the beginning of middle age, spends most of his time playing around with children, joining political processions and helping the villagers when he is not attending temple festivals. He is provided for by his younger sister who works as a house maid in the city ofThiruvananthapuram. His sister in an attempt to get his life organized arranges a marriage for him. But to the dismay of his new wife, Shankaran Kutty continues his life style often staying away from home for weeks. The already pregnant wife soon leaves him, and Shankaran Kutty does not make any attempt to have her back at home. Shankaran Kutty's life takes a turn from there on. His sister starts living in their family home with her new husband and slowly he finds himself out of place. Shankaran Kutty guilelessness starts brushing away, it is shown through a sub-plot in the movie. He realizes the hard realities of human life, when the widow who used to act as a patron for him commits suicide after being cheated in love. He reaches a turning point in his life when he joins as a truck driver assistant. Though he finds the job too much to handle at first, he slowly adapts to the new responsibilities of life. He starts making amends with his wife. The film ends when Shankaran Kutty has a happy reunion with his wife and newborn daughter. The film has a structure that resembles a typical Kerala temple festival. The title itself is an allusion to Shankaran Kutty recognizing and beginning his life of responsibilities like the traditional first ceremony in the temple festivals where a flag is hoisted to mark the beginning of the proceedings. The director commented that the film's most important connection to the festivals is the fact that in both nothing really happens; the only notable thing in both is the very presence of the people and events.
Critical commentary
Kodiyettam interweaves multiple aspects of a rural society with astonishing character growth of a man named Shankarankutty. In the initial parts of the movie Shankarankutty is portrayed as an immature man who lives a life mostly unaware of what is happening around him; a poor individual who is unable to associate and indulge in his surroundings. He was also a bit slow minded; in a scene when Shankarankutty was walking alongside a road a truck sped by him drenching him in muddy water however Shankarankutty admires the truck for its speed as if not realizing his shirt has been dirtied. Yet Shankarankutty always wanted to do things others were able to do. However he could do them only after he came in touch with a lorry driver. Shankarankutty always cherished an emotional connection with the widow who committed suicide because of the illicit relationship. Although he had doubts regarding her behavior he could never actually come up with any true evidence by sight but only by sounds. Whenever he got a chance to meet Sukumara Pillai and the widow together, there had to be some distractions which made it difficult for him to see what really happened between the two or what did they talk to each other, if they talked anything. His evidences for their relationship is supported by them talking to each other rather than being able to see them together . He knew the reason for her suicide only by overhearing the two speaking about her illegal conception. This fortune of not being able to see her with another man helps him to maintain ideal images of the two; a generous dutiful mother and widow Savithriyamma and the well-respected master, Sukumara Pillai. It is not from any morally perfect person that the transformation in Shanakarankutty is taking place but from a man with loose morals that he becomes what he is ultimately. Shankarankutty had many unfulfilled desires like-to have a relationship with the widow, to have promiscuous relationship like the lorry driver, to control something which he would never be able to do etc. He found most of these things have been done by others who had certain authority over their life, who would not rather spend their time on trifles like going for processions or attending festivals. One such men who had certain authority over his life is the lorry driver rather a well-respected person, like the master who had an affair with the widow.
