Kalyani (Kallu) is a devotee of the famous deity Ayyappan and is enthusiastic to visit the Sabarimala temple. As per religious beliefs, Kallu has a small window of two years to visit the temple as she is 8 years old. Her grandmother narrates the life of Lord Ayyappan to her, which she loves a lot. Ajayan is Kallu's father who has mortgaged their house and it is on the verge of being seized by the bank. Furthermore, Ajayan has also borrowed a huge sum from a local usurer and acquaintance Ambadi, and is unable to repay both the loans.
The bank has issued a seizure notice, which Ajayan hides from his family. Ajayan promises Kallu to take her to Sabarimala and that both will do the initial rituals for the pilgrimage, which is supposed to happen a few weeks from thereon. Ambadi publicly harasses and roughs up Ajayan, which is witnessed by Kallu. A humiliated Ajayan subsequently commits suicide out of disgrace. The bank eventually seizes Ajayan's house and Kallu's grandmother moves in with Ajayan's elder sister. Kallu and her mother move in with Ajayan's friend and neighbor Unni. Kallu becomes frustrated with the fact that she is unable to go to Sabarimala because of her father's death and yells at her classmate and Unni's son Piyoosh.
Piyoosh finds that it is impossible to dissuade Kallu from pursuing her journey to Sabarimala, and decides to accompany her. Both the kids board a bus to Pamba, and en route they meet Mahi, a local goon who is also a pedophile and trafficker. Under the pretext of heading to Sabarimala, he is on the lookout for young kids. His eyes fall on both Kallu and Piyoosh. Piyoosh senses that something is wrong and tries to persuade Kallu to stop the journey and head back home, but to no avail. Meanwhile, Unni and Kallu's mother informed the police about the missing children.
Later, a man named Ayyappan boards the bus, who also seems to be heading to Sabarimala, and gets acquainted with the kids. Mahi introduces himself as the kids’ guardian uncle to Ayyappan, which Ayyappan later finds out to be false and suspects that he has some malicious intentions. After hearing their story, Ayyappan promises the kids that he will accompany them to Sabarimala. Ayyappan intimidates Mahi and an infuriated Mahi is determined to incapacitate Ayyappan and kidnap the girl. On reaching Pamba, from where they have to walk to reach the shrine, the trio discovers that the police have restricted entry for the remainder of the day as a measure to control the crowd and they will not be able to visit the temple, but an adamant Kallu leaves Ayyappan with no choice except to take a route through the forest.
Mahi's accomplice who has been following them, informs Mahi about their movements, and he sends all of his henchmen to beat up Ayyappan and kidnap Kallu. Ayyappan is alerted of impending danger, where he successfully overpowers Mahi and his people. During the fight, Kallu visualizes Ayyappan as the actual embodiment of the deity Ayyappan and later reveals to him that she has seen him in her dreams, and shows him the drawings she made from them, which shows a man who looks just like Ayyappan. The following day, Ayyappan disappears into the crowd and the kids enter the shrine. As Kallu begins to worry and look for him, he shows up and encourages her to climb the steps to fulfill her father's wish. Later, the police hand the kids over to Unni and they are taken home. Due to the circumstances which followed, the kids believe that he was the deity Ayyappan himself.
It is then revealed that Ayyappan is actually CPO D. Ayyappadas, working at the police station in Pamba. He was alerted of the missing children and knowingly boarded the bus after having seen Kallu's photo. After hearing out their stories, he decided to make their wish come true by visiting the Sabarimala temple. Meanwhile, the police apprehended Mahi and his men, who happened to be on Tamil Nadu criminal records.
