Naachiyaar (2018) Timeline Explained – Every Event in Order

Kaathu was arrested because he was the only sexual partner Arasi had ever admitted to. When Arasi became pregnant, the police assumed he was the rapist since she was a minor. The case appeared straightforward until DNA tests later revealed Kaathu was not the biological father, which forced investigators to look for another perpetrator.

Foreshadowing: Earlier flashbacks show Arasi inviting Kaathu into her employer's house, making him the obvious initial suspect despite his claims of consensual sex.

The real rapist is Thangamani Prabhu, a wealthy North Indian moneylender. He raped Arasi while she was working as a maid.

Naachiyaar attacks Thangamani Prabhu because his wealth and political connections prevent the police from arresting him. When she and Feroz are ordered to stop the investigation by superiors, Naachiyaar takes matters into her own hands. She abducts him from a hotel and publicly castrates him as an act of vigilante justice, believing the legal system has failed Arasi completely.

Foreshadowing: Earlier scenes show the police being repeatedly blocked by the moneylender's influence, building frustration that culminates in her violent act.

Kaathu decides to raise the baby as his own because he loves Arasi and wants to protect her from the traumatic truth that she was raped by another man.

He believes the child deserves a father and that Arasi deserves peace, even if it means living with a lie.

Foreshadowing: The flashback shows Kaathu leaving hurt when Arasi rejected him after their intimate moment, but his feelings for her persist despite her rejection.

Feroz arrests Arasi's uncle and manipulates him into guiding the police to the fake abortion doctor.

The uncle's fate after this is not detailed, but he is no longer a threat once in police custody.

The moneylender Thangamani Prabhu is extremely wealthy and well-connected in politics.

The flashback scenes reveal how Kaathu and Arasi met as teenagers growing up in the slums without education. They show Arasi inviting Kaathu into her employer's home where they impulsively have sex, consensually, but Arasi immediately regrets it and pushes him away. This backstory explains why Kaathu becomes the initial suspect and provides context for his emotional investment in Arasi despite her rejection.

After publicly castrating Thangamani Prabhu in a hotel lobby, Naachiyaar faces an internal police inquiry for her actions. She is transferred from her position, likely to avoid public backlash and media scrutiny. Despite her controversial method, her popular stance on protecting the underage victim means the police department wants to distance themselves from her extreme actions.

This reunion represents her belief in second chances and family.
