John Biswas (Amitabh Bachchan) is a 70-year-old grandfather who visits the police station regularly. He is desperate to find the kidnapper and murderer of his grand daughter Angela who died 8 years ago. However, police inspector Sarita Sarkar (Vidya Balan) has no clues about the case. But he continues to search for the person who caused it, despite being dissuaded by people all around him, and collects evidence one by one in a small pace.
John’s wife Nancy is sick and bound to a wheel chair. Despite the personal problems John is determined not to give up. John also regularly meets Father Martin Das (Nawazuddin Siddiqui) who was once a cop and was handling the Angela kidnapping case. Martin Das tries his best in solving the case but the guilt of being unsuccessful makes him converted to a priest.
But one day, 8 years after that tragic incident, there is another kidnapping, that of a young boy named Ronnie, and everything about it echoes of similarity with the kidnapping of Angela. Further investigation reveals that the modus operandi for kidnapping Ronnie is the same as that of Angela. Inspector Sarita Sarkar requests Martin for his assistance. Martin supports partially by providing clues and Sarita along with John start investigating the case.
In the meanwhile, John doggedly pieces together the identity of Angela’s kidnapper from little bits of information that he collects through his own investigations and creates a plan to kidnap Ronnie. John wanted to seek revenge and justice since Ronnie’s grandfather Manohar (Sabyasachi Chakrabarty) was the one who kidnapped Angela. Since the modus operandi was the same Angela’s case file was re-opened. Manohar is then arrested and John makes him to confess about the crimes committed by him in front of the police. Manohar confesses about the crimes committed and is found guilty for his past activities. Manohar had kidnapped Angela since he needed money for his daughter’s open heart surgery.
It is also revealed that Angela was not murdered. While being held captive Angela escapes and accidentally falls from a height on to a car and dies. The car was driven by Father Martin Das.
