Ek: The Power of One 2009

Nandkumar ‘Nandu’ Sharma, an assassin, and his getaway partner Shekhar are hired by Anna Mhatre, an opposition leader, to carry out an assassination during a major party meeting in hopes of generating sympathy votes. On the day of the hit, the target is shot by an unseen assailant, and [Shekhar] dies in a separate accident.

Nandu escapes and leaps onto a train, where he encounters Puran Singh, who is returning home to Chambela in Hoshiarpur after years away. In Valsad, the police spot Nandu and open fire, unintentionally killing [Puran] instead.

The killer makes his way to Chambela to inform Puran’s family of the death. The family mistakes Nandu for Puran and welcomes his return with warmth. As he settles in, he grows closer to the household, helps resolve many of their everyday problems, and unexpectedly falls in love with Preet Kaur. He also reveals his true identity to Guru, who has been a longtime friend of the family.

Meanwhile, Mahendra Kumar Rane, a CBI inspector, is assigned to the case of Mhatre’s murder. His investigation points toward Chambela, and he becomes suspicious of Nandu. Using a clue from Savte from a prison context, Rane traces a payment that connects Nandu to Chambela.

Nandu flees before Rane arrives, and Rane informs the family of Puran’s death. After the investigators depart, the villagers briefly believe Nandu has deceived them, but [Guru] defends him, recounting the positive deeds he has done for the family. Nandu returns and insists that he did not cheat them, choosing to live honestly with his new ties.

Puran’s grandfather tells him that, rather than fleeing after the crime, he came to them and helped, and thus he should be treated as Puran. He encourages him to seek justice. Nandu then reaches out to Joshi, a CM candidate, and records a conversation to use as leverage against him.

Joshi reveals a shocking truth: Shekhar is alive and had killed Mhatre, then framed Nandu and faked his own death. Nandu records the entire phone call as evidence. He tracks down [Shekhar], but corrupt cops are sent to kill them and recover the tape. Nandu overpowers them and defeats [Shekhar], who dies in the struggle. [Mahendra Kumar Rane] arrives and is handed the tape as crucial evidence. When Rane confronts Joshi, Joshi asserts that the court won’t convict him, but Rane warns that Mhatre’s son will seek justice when he hears the tape. Cornered, Joshi takes his own life, ending the case.

The narrative closes with Nandu immersing in Puran’s ashes, and [Mahendra Kumar Rane] explains that the killer died in an accident and the mastermind committed suicide, allowing Nandu to depart as Puran. He then heads back to Chambela to begin a new life, carrying the weight of his choices and the hope of redemption.
