Amongst the conspirators is a young student of medicine, Alexis, who has incurred the suspicions of Vera's admirer, Michael, the most uncompromising of the revolutionists. Vera returns with the news that martial law is to be proclaimed. She is in love with Alexis and reproves him for running the risk of being present. Meanwhile, Michael and the President confer together. Michael proposes to don the uniform of the Imperial Guard, make his way into the courtyard of the palace, and shoot the Czar as he attends a council to be held in a room, the exact location of which he has learnt from Alexis. He has followed Alexis and seen him enter the palace, but has not seen the young man come out again though he had waited all night upon the watch. Vera defends Alexis whom the conspirators wish to kill. Suddenly soldiers are heard outside, the conspirators resume their masks as Kotemkin and his men enter. In reply to his inquiries Vera informs him that they are a company of strolling players. He orders her to unmask. Alexis steps forward, removes his mask, and proclaims himself to be the Czarevitch! The conspirators fear he will betray them, but he backs up Vera's tale as to their being strolling players, gives the officer to understand that he has an affair of gallantry on hand with Vera, and with a caution to the General dismisses him and his men. The curtain comes down, as, turning to the Nihilists, he exclaims, "Brothers, you trust me now!" The second act is laid in the Council Chamber, where the various councillors are assembled, including the cynical Prime Minister, Prince Paul Maraloffski. Presently the Czarevitch enters, followed later by the Czar, whose fears Prince Paul has worked on to induce him to proclaim martial law. He is about to sign the document when the Czarevitch intervenes with a passionate appeal for the people and their rights, and finally proclaims himself a Nihilist. His father orders his arrest, and his orders are about to be carried out when a shot is heard from without and the Czar, who has thrown open the window, falls mortally wounded, and dies, denouncing his son as his murderer.
