A woman, while searching for her missing husband, an honest police officer, faces inhumane treatment from the local police. During her search, she encounters a goon named Saleem and discovers that he killed her husband. As Saleem attempts to kill her, she manages to escape and takes refuge in a local temple. It is revealed that she is pregnant with a son named Puli. Saleem makes another attempt to kill her and assumes she is dead after she falls from a short waterfall. Unbeknownst to him, she survives and vows to make Puli a police officer. Years later, when terrorists in
Malaysia attack the
Prime Minister of India, Puli, now an
IPS officer, kills all the terrorists, saving the PM's life and restoring the honor of the police. At the subsequent award ceremony, Puli demands and establishes a special task force equipped with advanced technology, composed of honest and capable police officers. He sets up a ₹1 police phone booth outside police stations for those who do not receive justice or experience complacency from police officers. Puli leads the special team with his trusted officers. Simultaneously, a woman falls for Puli and, pretending to be
S.I. Madhumati, makes Puli fall for her, knowing he is determined to marry a policewoman. Though he eventually discovers her deception, he forgives her and they fall in love. Saleem, now a feared gangster working with another gangster named Nixon, commits crimes at an unprecedented level, including illegal arms deals and black money operations. He either kills or bribes police officers to keep them in line.
ACP Ravi Kumar fears him, and the
IG has joined hands with him, making many police officers too afraid to file cases against him. Saleem’s crimes are meticulously managed, leaving little or no trace. Puli convinces Ravi Kumar to reopen an old case against Saleem, reminding him of the true meaning of being a police officer. However, their efforts are thwarted due to a lack of evidence. After a minor incident involving Saleem’s car being parked in a no-parking zone, Puli frustrates Saleem, indirectly confronting his father’s killer without realizing it. Puli becomes increasingly frustrated as his team’s secrets are leaked and his team members are killed one by one. During a shootout, Puli discovers that Nixon is a mole in his team and kills him. Finally, Puli and Saleem face off directly, with Saleem capturing Puli’s mother. At this point, Puli’s mother reveals the truth about Saleem. Enraged, Puli fights Saleem and forces him to confess to all his crimes, which are broadcast live via a pinhole camera. Thus, Puli avenges his father and restores justice. ==Cast==
