Tessa (Parvathy) is a graphic artist who runs from home to avoid her marriage. With the help of her friend, she rents a room. Initially, she hates her room which is a complete mess, but then she learns that the room was previously occupied by a carefree vagabond named Charlie (Dulquer Salmaan). When she starts cleaning up the place, she discovers a photo and a sketchbook of this man. The sketches depict the previous New Year’s Eve when a small-time thief (Soubin Shahir) tries to rob the man’s room. In a turn-of-events, the man joins him, and they both go on the rooftop of a home. There, they are shocked by what they see inside. That was the last page of the sketch, and the story is left unfinished, which piques her curiosity about the rest of the story, as well as the previous occupant of the room.
Intrigued, Tessa starts finding the people in the man’s sketches. Backtracking his steps, she meets the man’s “father” (who is more of a friend), a boat servant, and Mariya/Queen Mary (Kalpana), a physically abused woman. Charlie takes Mariya out to sea for her birthday. Unfortunately, Mariya commits suicide and he becomes heartbroken. Following up on more clues, Tessa gets news that the man is staying in a hotel and rushes to meet him. However, she just misses him by a few seconds. Later a helper boy in the hotel explains to her that the little girl with Charlie was Mariya’s daughter.
