Anuradha Verma (Aishwarya Rai Bachchan) is a prominent criminal lawyer and a single mother who has never lost a case. One day her daughter Sanaya (Sara Arjun) is kidnapped and no ransom is demanded, but instead the kidnapper contacts her and tells her that she has to defend a convicted felon to get her daughter back. The felon is Miyaaz Shaikh (Chandan Roy Sanyal) who is convicted for rape and murder of a young woman and the case against him is set for judgment in four days. The kidnapper keeps track of Anuradha very closely to make sure she complies with his demand. With the pressure of time against her, Anuradha tries to get help from her suspended police friend Yohan (Irrfan Khan) who has been suspended from the police force for flaunting the rules and regulations too often.

The case against Miyaaz Shaikh is handled by a renowned public prosecutor Ronit (Atul Kulkarni) who has been defeated by Anuradha and hence has a long time professional rivalry against her. Anuradha races against time and saves her daughter by twisting the laws to win the case. Miyaaz Shaikh is a serial rapist and murderer and has done jail time before. He has been arrested for the rape and murder of Sia (Priya Banerjee). Yohan was the inspector who arrested Miyaaz. Yohan has been begging Anu to take his suspension case, which Anu is refusing, but agrees to cooperate with her in the Miyaaz case. Yohan and Anu meet the doctor who conducted the autopsy and then meet Garima (Shabana Azmi), Sia's mother. Garima doesn't know Anu is Miyaaz's new lawyer & speaks to her. She wants Miyaaz to hang, but Miyaaz's death means Sanaya's death to Anu. Home Minister Mahesh Malkai (Jackie Shroff) is involved and asks Ronit to ensure that Miyaaz should hang. Yohan is convinced that Miyaaz is guilty, but Anu is not so sure as the killer removed all traces of DNA from Sia's body by washing it with alcohol. Yet Miyaaz fingerprints were all over the murder and rape scene.

Anu checks's Sia's computer and finds her photos of Sam (Siddhanth Kapoor). Sam is now in a mental facility, having fried his brain with the reckless use of drugs. He was admitted one week before Sia was murdered. As the trial starts, Garima realizes that Anu is Miyaaz's lawyer. Anu tries to establish that Sia was a party person, having sex with many men & that no one forced his way into her house on the night of her murder. So, she was raped and murdered by one of her known friends & not by Miyaaz, who was in Sia's house to steal some money for her ill mother. Ronit produces Miyaaz's wife in court who claims that Miyaaz supplied drugs to Sia and had gone out to recover money from her on the night of her murder. Miyaaz admits to Anu in private that he raped and murdered Sia. Anu doesn't tell this to anyone and still has Yohan looking for clues to acquit Miyaaz. Yohan finds that Sam was not in hospital a week before Sia's murder and had in fact attended her funeral.

Yohan finds that Mahesh Maklai is Sam's father. Mahesh tells Anu that Sam did bring Sia's body to his house on the night of her murder, but he was completely under the influence of drugs and had no re-collection of the events prior to that. So Mahesh got the body washed with alcohol and disposed under a bridge. Mahesh then destroys all evidence linking Sam to Sia's murder. In court, Anu argues that Sam and Miyaaz were at Sia's apartment at the time of her murder. She contends that either of them could have killed Sia and there was no concrete proof that linked either of them positively to the murder itself. To prove her theory, she produces Sam in court (whom Yohan has managed to track down). Sam agrees that he was in the apartment on the night & when he woke up, he found her dead. He took her body to his house, where his father doused Sia with alcohol and abandoned her body. This creates enough uncertainty to ensure that the court is unable to convict Miyaaz and releases him on bail till a murder weapon is found with the killer's fingerprints on it.

As soon as Miyaaz is released, he is ambushed and abducted by an assassin named Vijay. Yohan traces Vijay, who tells him that Garima is the brains behind the operation. Sanaya is released and found alive. Anu confronts Garima, who admits that she burnt Miyaaz alive to get revenge for Sia. She promises Anu that she kept Sanaya as her own daughter. Police arrests Garima and Anu decides to represent her in court.
