Plot
Tessa is a graphic artist who runs away from home to avoid an unwanted matrimonial alliance. With the help of her journalist friend, she acquires a rented apartment in a dilapidated house. Initially, she hates the tattered place, but soon she learns that the room was previously occupied by a carefree vagabond named Charlie. When she starts cleaning up, she discovers a photo and a graphic novel about this man. The sketches in the novel depict the events from the previous New Year's Eve when a small-time thief tried to rob the man's room. In a turn-of-events, the man joined him in his nightly theft routine and snuck up on the roof of another house. But there, they encountered something shocking that left them stunned. The novel stops there abruptly with sketches of the dumbstruck faces of Charlie and the thief on the last page. This piques Tessa's curiosity about the rest of the story, as well as the previous occupant of the room.
Intrigued, Tessa starts looking for the people in the man's sketches. Backtracking his steps, she meets the man's "father" (who is more of a friend). She also comes across a boat servant named "Pathrose" who tells her the story of Mariya/Queen Mary. Mariya was a middle-aged woman, who was sexually exploited by her procurer husband in her youth. Once, Charlie took the now terminally ill Mariya to the sea at midnight with the help of Pathrose for her birthday. But Mariya jumped into the ocean to her death, that left Charlie stunned with shock and grief. Following up on more clues, Tessa gets news that Charlie is staying in a hotel and rushes to meet him. However, she misses him just by a few seconds. Later a helper boy in the hotel explains to her that Charlie had just rescued Mariya's daughter from her father's exploitation, after creating a ruckus.
A few days later, by the stroke of luck, Tessa meets the thief depicted in that man's sketches and inquiries about the rest of the story from New Year's Eve. He tells her that on that day, they had encountered a young woman on the verge of suicide, and his sir (Charlie) stopped her from hanging herself, after which she escaped from the scene on her bike. Tessa and the thief locate the woman's house and finally identify her as Dr. Kani from the latter's father.
Tessa travels to Ooty to find Kani and inquires about her story. Kani explains that she was depressed over her broken relationship when she did her first independent operation, leading to the death of a 10-year-old girl. Further hooked by the media, she was desperate and about to commit suicide on new year's Eve when she was distracted by that man (Charlie). He brought her to a shelter home maintained by Kunjappan in Ooty and she has been living there since. Kunjappan, an old man, is a hopeless romantic who is waiting for his teenage love Thresia to show up.
Tessa spends a good time in Ooty but her trip comes to an abrupt end as her brother and mother find her and take her home against her wishes. While a depressed Tessa is on her way back home, Charlie returns with Kunjappan's long lost love Thresia, who is a nun now, and they again miss each other by a few seconds.
Later, Kani informs Charlie about Tessa, and he admits knowing about her and her search for him. Though initially reluctant to love, Charlie is forced to rethink after hearing Kunjappan and Kani. Next morning, he sneaks out early and informs Kani that he will be attending the Thrissur Pooram function, and Tessa can find him there if she's looking for him.
Tessa reaches the Pooram grounds and finds him performing in a magic show. Afterward, he spots her, approaches, and asks her if she wants to have some drink. At first, she introduces herself as Shruti Raman and lets him think that he has met the wrong person. But as the festival starts, Charlie's antics make her confess that she is indeed Tessa and he too reveals his name to be 'Charlie'. As the credits roll, they are seen wandering together towards a new journey in life.
