Plot
Mamta kumar (Divya Khosla Kumar) is a widow living in poverty with her young son Sonu and her mother-in-law. She is constantly hiding from Thakur’s debt collectors—her late husband owed them money she still cannot repay.
Abhishek Verma (Neil Nitin Mukesh), a government contractor, is extremely wealthy thanks to the money he and his political allies—including Minister Qureshi (Zakir Hussain)—have stolen from the government and the public.
One day, on his way to an important meeting with Qureshi, Abhishek’s car is involved in an accident. To reach the meeting on time, he decides to take the metro. At the station, his phone is stolen. Mamta, who works as a staff member at the metro station, sees this on CCTV and rushes out to chase the thief, but returns empty-handed.
It is then revealed that Mamta had secretly conspired with the thief. She had asked him to steal a phone so she could gift it to her son for his birthday—something she could not afford.
Meanwhile, Abhishek panics, realizing the stolen phone contains confidential information about his corrupt dealings and his affair with his secretary Tina Gupta (Heli Daruwala). He asks his policeman friend Triloki (Sushant Singh) to urgently recover the phone. Triloki begins the investigation.
At home, Mamta discovers the incriminating data on the phone—videos, messages, proof of corruption, and evidence of Abhishek’s affair. She changes her plan and contacts Abhishek, demanding Rs 2 crore in ransom. Abhishek refuses.
Triloki quickly uncovers Mamta’s involvement and raids her house. Not finding Mamta at home, the police detains her mother-in-law and demands Mamta surrender herself with the phone in exchange for her release.
When Abhishek returns home, he is shocked to see Mamta there—hired by his wife as a cleaner. Terrified she might expose his affair, he pretends not to know her and tries to act normal. Mamta uses this to her advantage, forcing Abhishek to secure the release of her mother-in-law.
Over the next few days, Mamta cleverly fuels tension between Abhishek, Tina, and Qureshi, making them suspicious of one another.
After several failed attempts to forcibly retrieve the phone, Abhishek kidnaps Sonu from school, demanding Mamta hand over the device. Mamta rushes to the location and is beaten by Abhishek’s men, but still refuses to give up the phone. Abhishek then threatens to kill Sonu—but Mamta laughs and reveals she tricked him into kidnapping the wrong child. The boy he took is actually Thakur’s son, the gangster to whom her husband owed money.
Soon, Tina, Qureshi, Triloki, and Thakur all arrive at the scene. Mamta reveals, using Abhishek’s own messages, that Abhishek has been betraying Qureshi. A heated argument breaks out among the group. Triloki then reveals that he has recorded everything on his phone. Using the recording as evidence, he orders raids on both Qureshi’s and Abhishek’s properties.
In the final twist, Mamta reveals that it was Abhishek whose scam drove her husband into debt and ultimately suicide. Triloki’s father was also one of Abhishek’s victims. The theft of Abhishek’s phone was not random—the entire operation was carefully planned by Mamta and Triloki to expose his crimes.
With no escape, Abhishek grabs Sonu and holds him at gunpoint while attempting to flee. He is struck and killed by an oncoming train. The corruption scandal is exposed, leading to the arrest of Qureshi and Tina.
