Betala begins to narrate one of his puzzling tales to Vikramāditya which is the story of Naanu (translates to I/Me/Myself), an ego-driven selfish rogue and the three women in his life. Naanu since childhood hates hypocrisy and always speaks the truth. In the process, he exposes the truth behind everything. A young woman Rathi comes to know her father's hatred towards her in this process and falls in love with Naanu. However she finds out that Naanu wants to marry a billionaire Keerthi whose deceased father decides that her husband would inherit her entire wealth. He prints wedding cards and distributes it to all, including the employees working in Keerthi's establishments. This angers Keerthi who orders her guardian's son (who wants to marry her for the same reason) to attack Naanu. They bring a woman Swathi, who lives in his house and toture her. Naanu comes to her rescue and it is revealed that Swathi is Naanu's wife.
Rathi meets him in person and confirms the facts. She threatens to kill both the women and commit a suicide if Naanu leaves her for anyone of those two women. He agrees, and Swathi leaves. She rescues the duo from Keerthi's henchmen and in turn, Naanu peruades her to return. She too threatens to kill both the women if Naanu leaves her for anyone of those two, to which Naanu agrees. He continues to be in a relationship with Rathi and hides it from Swathi and vice versa. However, his obsession for Keerthi never dies. He traps her guardian and after a turn of events, Keerthi agrees to marry him. While they both are in a jubilant mood, Rathi and Swathi come to know about this and reach the harbour where the duo is currently hiding in from the henchmen of Keerthi's guardian. When they reach the harbour, Keerthi is informed about Naanu's plans and she drops her marriage plans with him. He kidnaps all the three women and kills Keerthi's guardian and her son.
Naanu and the three women reach an old building where an injured Naanu threatens to kill all of them and forces all to be his life partners to which they do not agree. Meanwhile, a rich person meets Naanu there who happens to be a poor man in the past. Naanu in the past advised him not to follow behind women and instead focus on earning money, adding that women will run for you if you are a wealthy man. At the same time, he sees an once-wealthy man whose wealth is usurped by his girlfriends. This pushes Naanu in a dilemma and sits in a room in the first floor. The three women, with rods in their hands, decide to kill him. Vethala stops the story here and asks Vikramāditya whether Naanu would survive or die in their hands. Vikramāditya understands the tale's intention and says that Naanu, Rathi, Swathi and Keerthi are not humans and instead represent human ego, beauty, responsibilities and money respectively. He concludes that Naanu should kill himself and take a rebirth again.
Naanu sees himself in a mirror and feels ashamed of his traits. He curses himself for pursuing all the three who never gave him any happiness. He realises the importance of "Us" instead of "I" and decides that ego is the root cause of all issues. By tearing the shirt featuring an imprint of his face, he kills his inner ego and the feeling of "I". The three woman disappear and Naanu, now silent and aimless, walks out of the building drenching in the rain.
