Sri witnesses what appears to be a girl being abducted by four men in the early morning and suspects the victim is Parvathy. However, this was actually a scene from Vetri's short film that he was filming. The confusion arises because Sri didn't know about the film shoot happening in the area, leading him to believe a real crime had occurred.

Earlier that morning, Vetri had spotted Parvathy at Vasanthi Bakery, placing her at the location where the film shoot took place.

Parvathy did not get abducted. She ran away from home to escape her alcoholic father Vasanth, who attempted to misbehave with her. Her mother Shobha secretly helped her escape to protect her from Vasanth's abuse, arranging for her to stay at her uncle's house.

Vasanth's behavior as an alcoholic father is established early, showing his unstable state.

Inspector Selvam is Vetri's father. This is revealed when Vetri tracks down the script thief Thyagu, who reveals he handed the stolen script to Selvam. Selvam later confirms this relationship and shares that Vetri's mother Ilakkiya died from grief over Vetri's passion for cinema.

Selvam's emotional reaction to the attack on his son Vetri hints at their deeper connection.

Vasanth commits suicide after being confronted by Sri about his horrific behavior toward his daughter Parvathy. Consumed by guilt, he writes an apology acknowledging that his addiction had driven him to behave inexcusably. The shame and realization of his actions lead him to take his own life.

Sri confronts Vasanth about his abuse of Parvathy, revealing the truth behind her disappearance.

Thyagu stole Vetri's script from his residence. He later handed it over to Inspector Selvam. The investigation reveals that Director Kishore orchestrated the theft, using his assistant director Sathya (Vetri's friend) to orchestrate the plan. Selvam submitted the script and audio recordings to the FEFSI association for action against the plagiarism.

Vetri's neighbor mentions a snake tattoo on the thief's left hand, helping identify Thyagu.

Bala, son of Minister Iyyappan, orchestrates the attack on Vetri as revenge against Inspector Selvam. Earlier, Selvam had publicly reprimanded Bala and his brother Ashok Krishna for a hit-and-run case, despite accepting a bribe to release them initially. Bala's goons arrive at Vetri's house, where Sri and his friends are also present, but Vetri manages to subdue the attackers.

Selvam's confrontation with Bala at the police station establishes the escalating conflict.

Selvam is fatally shot by Minister Iyyappan's men at night. This happens after Selvam refuses to release the minister despite pressure, citing the filed FIR. The minister's men kill Selvam to avenge the public reprimand of his sons. In the final scenes, Vetri pays his respects at his parents' graves, showing Selvam's memory lingers alongside his mother Ilakkiya.

Selvam's confrontation with the minister and his sons establishes the dangerous conflict.

Shobha, Parvathy's mother and Vasanth's wife, secretly helped Parvathy escape because she wanted to protect her daughter from Vasanth's abusive behavior. When Sri confronts Parvathy at her uncle's house, it is revealed that Parvathy ran away to flee her alcoholic father who attempted to misbehave with her. Shobha arranged the escape to ensure her daughter's safety.

Vasanth's addiction and unstable behavior are established early in the film.

Thyagu reveals to police that he saw Parvathy getting into a grey Hyundai i20 earlier that morning. This leads investigators to contact Vasanth's wife Shobha, who contacts her brother, the owner of the grey Hyundai i20. The car belonged to Parvathy's uncle, where she had gone to escape her father, not as a victim of abduction.

The investigation follows the grey car lead, connecting to Shobha's brother.

Selvam reveals a painful family secret: Vetri's mother Ilakkiya died from grief over Vetri's passion for cinema. She could not accept his dedication to filmmaking and the path he chose, leading to her emotional decline and eventual death. This tragedy adds to Vetri's emotional journey throughout the film.

Vetri's struggle with addiction and his passion for cinema are central to his character arc.
