Leo

Parthiban, known as Parthi, leads a quiet life in Theog, Himachal Pradesh, with his wife Sathya and their two children, Siddharth and Mathi. As an animal rescuer and cafe owner, he dedicates his days to running his cafe, Bold Street, and caring for local wildlife.

One day, Parthi's friend Joshy, a local forest ranger, seeks his help with a dangerous spotted hyena terrorizing the town. This hyena has already attacked several residents and is acting unusually aggressive, leading Parthi to recognize the animal may need help instead of danger.

Understanding the social nature of hyenas, Parthi, with the assistance of his son Siddharth, manages to tranquilize the frightened hyena. After bringing it to safety and ensuring its well-being, they adopt the hyena, naming it Chakadbangadu.

Parthi’s life takes a turn when the ruthless robber Shanmugham and his gang target Bold Street for a heist. The atmosphere escalates quickly as the gang's violent past becomes evident through their menacing actions during the robbery.

When one of Shanmugham’s men attempts to harm Parthi’s employee Shruthi, he can no longer stay passive. Parthi's protective instincts kick in, leading to a fierce confrontation where he ultimately kills Shanmugham’s gang members.

Despite acting in self-defense, the aftermath sees Parthi arrested. His actions draw media attention, painting him as a vigilante, which complicates his relationships and draws the interest of the local criminal underworld.

Gangster Harold Das believes Parthi is actually his long-lost brother, Leo Das, bringing an additional layer of peril to Parthi's life. This mistaken identity leads to a tense game of survival, as both Harold's and Shanmugham’s families pursue retribution against Parthi.

In desperation, Parthi approaches the police for help only to be ridiculed by Officer Bhawar Jetha. Facing mounting threats, he takes matters into his own hands, fortifying his home in preparation for the inevitable retaliation.

Antony, played by Sanjay Dutt, arrives on the scene, convinced that Parthi is indeed Leo. This confrontation stirs up buried family secrets and causes his loved ones to question their understanding of the past.

In a harrowing twist, Parthi’s teenage son, Siddharth, is kidnapped by Harold’s men. With his family in danger, Parthi finds himself once more in the fight of his life, driven by the need to protect his loved ones.

Parthi teams up with Napoleon, an officer determined to help him rescue Siddharth. Together, they devise a plan to confront Harold’s men, showcasing the lengths a father will go to protect his family.

As the confrontation unfolds, chaos ensues, with violence erupting in every direction. Unexpectedly, Chakadbangadu, the hyena, plays a crucial role in defending Parthi's family, turning the tide of events.

In a dramatic climax, Parthi faces Harold in a final showdown, where he reveals his true identity as Leo. This confrontation is not only personal but serves as a battle for justice against a backdrop of familial betrayal.

With the criminal factory in flames, symbolizing the end of one chapter of violence, Parthi grasps for a peaceful future. Yet, the shadows of his past linger as he endeavors to pave the way for his family.

Even as Parthi seeks to move on, an ominous caller hints at the pervasive drug issues plaguing the nation. This revelation leaves him with the realization that his battles are far from finished, and the fight continues.
