Aadu 3

In the year 2370, Earth is ruled by a totalitarian regime known as The Organization, which has exhausted the planet’s natural resources. To sustain its dominance, the Organization searches for a rare celestial substance called Star Dust, believed to possess the ability to manipulate and rewrite timelines.

A resistance movement led by Baba discovers that time in this universe is not linear — past, present, and future coexist simultaneously, and actions in one timeline can alter the others. Realizing the danger, Baba devises a plan to prevent the Organization from ever acquiring the Star Dust by interfering with events in the past.

In the 1790 CE, Maharaja Padmanabhan Thampuran, a seemingly impoverished ruler, governs a small kingdom while secretly guarding a powerful secret. Alongside Vareed Mappila, an architect, and Walter Joseph, an English East India Company general, he oversees the construction of the Nagathan Bridge.

At the same time, the kingdom faces internal unrest due to heavy taxation, leading to a peasant revolt. Externally, it is threatened by an invasion led by Sulthan Azam Khan, a commander under Tipu Sultan, who brings with him the devastating Mysore rocket, a weapon truly capable of massive destruction. Meanwhile, a British fortune hunter, Cassandra, arrives in the kingdom in search of the Star Dust, believed to have landed there centuries earlier as a meteor.

As war looms, Padmanabhan reveals to his trusted aide Karyasthan Narayanan that his ancestors secretly hid the Star Dust and concealed their wealth by pretending to be destitute. He stores the Star Dust in sealed boxes and entrusts them to Vareed Mappila, who hides them within the structure of the Nagathan Bridge during its construction, but unknown to anyone, Padmanabhan Thampuran also hides something else in the forest.

In the present day, Shaji Pappan and his associates come into possession of 3 million US dollars after defeating Chekuthan Lasar and his group.^[a] They attempt to travel abroad to convert the money but soon discover that the cash is counterfeit.

Elsewhere, Saathan Xavier, struggling with depression after losing the printing plates, learns from his cousin Michael about the hidden boxes storing Star Dust, believed to be stored inside the Nagathan Bridge. Seeing an opportunity, Saathan orchestrates a plan to demolish the bridge by influencing politician P. P. Sasi, promising him a share of the profits. Police officer SI Sarbath Shameer is assigned to oversee the operation and secure the contents.

Seeking quick money, Pappan establishes a scrap collection company and secures the contract to clear the bridge’s debris after demolition, threatening Battery Simon and Kanjavu Soman. However, Soman independently contacts Dude and convinces him to steal the boxes for themselves.

After the bridge is demolished, Dude arrives in a helicopter and retrieves the boxes, but Thomas Pappan, Shaji Pappan's brother, shoots the rope pulling Dude, causing Dude and the boxes to fall into the river. Amid the chaos, with Saathan Xavier, Shaji Pappan, Dude and SI Shameer trying to take the boxes for themselves, they are ultimately taken by Kate Lara, an operative of the Organization. When she opens them, she discovers that they are empty.

Simultaneously, in 1790, Maharaja Padmanabhan Thampuran confronts Azam Khan at a ruined gate in the forest, while in 2025, Pappan and Dude face off at the same location, now in front of the police station. It is revealed that what Padmanabhan Thampuran hid in the forest was the actual Star Dust, and the boxes in Nagathan Bridge were just a decoy. As both confrontations escalate, the hidden Star Dust beneath the gate is activated. The anomaly creates a temporal rupture, pulling them across timelines. Padmanabhan and Azam Khan are drawn into the modern era, while Pappan and Dude are transported into the 18th century. Some time later we see Shaji Pappan fighting Sulthan Azam Khan's soldiers.
