Dada Sahib is a 2000 Malayalam-language political action drama film co-written and directed by Vinayan, starring Mammootty in dual roles as a father and son.
He played the roles of Dada Sahib, of the Indian independence movement and his son Abubacker, an army man.
But Rahmath Ali informs Sahib that he couldn't do anything as Abubacker's death sentence is declared, and even the Supreme Court of India had rejected his mercy petition.
Back to the present, Doctor Raveendran discloses his pain to Das, a sincere and heartful police officer, of losing his wife in the bomb blast of Thaliyoor temple.
Eager to publish it and accusing him for another death sentence, he learns the truth from Raveendran when Abu recalls a past where Minister Mohammed Kutty was one of the reasons behind the explosion that happened at the temple.
But on the way, Raveendran is killed, and Athira is taken to Mohammed Kutty's and Atmaswaroopan's custody to know if Abu is alive or not but in vain.
The Chief Minister warned Sahib not to kill a Governor, and if the accusation comes true, the law will take actions.
However, Sahib didn't listen to the Chief Minister's words and decided to kill Rahmat Ali after advising them about the importance of unity and strength in fighting for India.
However, the dying Sahib musters up strength and manages to behead Rahmath Ali and succumbs to his injuries at the spot.
