Indru Netru Naalai (2015) Timeline Explained – Every Event in Order

Elango uses the time machine to travel to the future and gather stock market information, which he then presents as his own predictions during a board meeting. This calculated move is designed to impress Anu's powerful father, Rajarathinam, who previously dismissed Elango's business ideas. The successful prediction earns Rajarathinam's approval and removes the obstacle preventing Elango from marrying Anu.

Foreshadowing: Earlier, Elango struggles to get his ideas heard while maintaining a fragile relationship with his wealthy girlfriend Anu, establishing his desperation for validation.

When Elango and Arumugam attempt to fix their earlier mistake by traveling back in time, their interference inadvertently prevents Kuzhandaivelu's assassination attempt on Rajarathinam. The gangster's original plan fails not because of careful planning, but because the time-travelers' reckless manipulation creates a chain of events that saves Rajarathinam's life, along with Kuzhandaivelu's, who would have been killed during the failed assassination.

Foreshadowing: The film establishes early that time travel creates unpredictable consequences, starting with Parthasarathy's coma.

Anu is killed when Kuzhandaivelu tracks down Elango and Arumugam at a shopping mall and opens fire. The gangster targets them after they repeatedly interfered with his plans to eliminate Rajarathinam. Anu's death is a direct consequence of Elango and Arumugam's time-traveling escapades, as Kuzhandaivelu views anyone connected to them as collateral damage in his mission.

Foreshadowing: Earlier, Kuzhandaivelu vows to eliminate not only Rajarathinam but also Elango and Arumugam for stepping into his path.

In the chaotic final confrontation, Elango manipulates Kuzhandaivelu into chasing him toward his own past self who is about to fire at the time machine. When present-day Kuzhandaivelu encounters his past version, Elango triggers a situation where the gangster fires at his own past self, causing both versions to die simultaneously. This paradox eliminates the immediate threat while erasing the timeline where the killings occurred.

Foreshadowing: The film's time travel rules establish that actions in the past directly affect the present, making this paradox possible.

In the new timeline created after Elango and Arumugam choose not to claim the time machine, they never encounter Parthasarathy during the original accident. Since Parthasarathy only met them because of the time machine incident that left him in a coma, without that meeting, he has no memory of them. The timeline reset effectively erases their entire relationship from existence.

Foreshadowing: Parthasarathy's coma was directly caused by the time machine's arrival, linking his fate to their involvement with the device.

The time machine is destroyed during the chaotic confrontation when all three, Elango, Arumugam, and Kuzhandaivelu, are thrust back into the past. Kuzhandaivelu destroys the machine in the struggle. However, in the final frame, the device mysteriously returns to 2065 as if it had always belonged there, appearing in the scientist's laboratory. The machine never resurfaces in the new timeline, effectively vanishing from existence in that reality.

Foreshadowing: The scientist's original experiment was to send the machine back to 2015 and have it return within forty seconds, its eventual return fulfills this purpose while remaining unseen in the altered timeline.

After defeating Kuzhandaivelu, Elango and Arumugam realize their earlier actions created the troubled timeline they inhabited. They deliberately choose not to uncover or claim the time machine when it appears in 2015, effectively erasing their entire involvement with the device. This decision prevents Parthasarathy's accident, Kuzhandaivelu's entry into their lives, and all the subsequent consequences, creating a new timeline where they never used time travel at all.

Foreshadowing: The film establishes that time travel creates alternate timelines, with earlier choices directly shaping later events.

After Kuzhandaivelu damages the time machine during a confrontation, Parthasarathy repairs it but the rebuilt device can only shuttle to a fixed moment, the exact time when Kuzhandaivelu first damaged it. This limitation traps Elango and Arumugam, eliminating their ability to return to the future or freely navigate time. The damage creates a closed loop that forces them to use the limited options available.

Foreshadowing: The machine was damaged when Kuzhandaivelu fired at it during the confrontation in the present.

The scientist originally sent the time machine to 2015 with instructions to return within forty seconds to prove the device worked. In the final timeline, the machine does return to 2065, technically validating the experiment as a success. However, the scientist remains unaware that the machine's journey caused significant upheaval in 2015. His celebration is for what he believes was a successful demonstration of time travel, not for any actual change in the future.

Foreshadowing: The opening scene establishes the scientist's goal: proving the time machine's power by sending it to the past and back.

Kuzhandaivelu targets Rajarathinam for assassination, but Elango and Arumugam's time-travel interference accidentally saves both Rajarathinam and Kuzhandaivelu during the attempt. Enraged by this interference and the failure of his plans, Kuzhandaivelu decides to kill Rajarathinam himself while also eliminating the two time-travelers who meddled in his business. Their paths collide repeatedly until they become mortal enemies.

Foreshadowing: The failed assassination is directly caused by the duo's past-hopping, establishing the causal chain that leads to the conflict.

• elango
• arumugam

The duo uses the time machine to travel briefly into the past to discover where people misplaced valuable items. They then present these discoveries as miraculous revelations during Arumugam's astrology consultations, claiming divine insight. This scheme successfully builds Arumugam's reputation as a clairvoyant, drawing numerous clients who believe in his supposed supernatural abilities.

Foreshadowing: Arumugam is established as a fake astrologer who makes a living through deception before obtaining the time machine.

In the new timeline where Elango and Arumugam never used the time machine, Elango still finds a way to succeed. He obtains a legitimate job and impresses Rajarathinam with a genuine business idea, earning his approval without any time travel manipulation. This leads naturally to his marriage with Anu, achieving the same outcome through ordinary means.

Foreshadowing: Elango's original motivation for using the time machine was to gain Rajarathinam's approval to marry Anu.
