USTOM starts off with a periodic era of 1959, when Mumbai was still ‘Bombay’ and the times when justice was done by the jury members and not by the judge. This is followed by the introduction of the ‘habituated to his uniform’ Commander Rustom Pavri (Akshay Kumar) and his lovely wife Cynthia Pavri (Ileana D’Cruz). One day, when Rustom Pavri comes back home from the sea, earlier than his scheduled date, he is shocked when he gets to know that his wife Cynthia has gone out with the ‘filthy’ rich Vikram Makhija (Arjan Bajwa) and has not been home since two days. Rustom Pavri, then, starts breathing fire and reaches Vikram’s house, only to find Vikram and Cynthia together. Unable to bear the sight of his wife’s deceit, Rustom Pavri loads his official gun and shoots the evil minded Vikram, killing him. Being the ever righteous man, Rustom Pavri then goes to the police station and surrenders himself. When the news of Vikram’s death reaches the ears of his ‘well connected’ sister Preethi Makhija (Esha Gupta), she vows to revenge her brother’s death. As the case goes to the court however, Rustom pleads not guilty. What follows after that is a heated court room drama, mudslinging, the role of the media in the case… all eventually leading to one common thing. What is the ultimate conclusion of all the events, is Rustom Pavri really guilty or is there more than what meets the eye.
