Redl and Kubinyi slowly climb the ladder as career officers. Once they become adults, the two friends have different political ideals. As a Hungarian, Kubinyi slowly falls prey to the national aspirations of a Hungary free from Habsburg rule, while Redl remains fiercely patriotic and faithful to his benefactor, the Austrian Emperor. For Redl, his relationship with Kubinyi goes beyond friendship as Redl harbors an unrequited love for his comrade. When the two young men visit a brothel, Redl seems more interested in watching his friend having sex than in engaging a woman in his own room. Redl suppresses his attraction to Kristof, however, and transfers it, as best as he can, to Katalin, his friend's beautiful sister. Back at the academy, Alfred serves as a second in a duel between Kristof and another classmate, who is killed in the contest. This foolishness jeopardizes the careers of both Kubinyi and Redl, but the commanding officer, Colonel von Roden, having noted Redl's hard work and loyalty to the Emperor, arranges a promotion for him and a prized assignment in Vienna. In Vienna, Redl is able to renew his friendship with Katalin, who is, by then, unhappily married. They become lovers in spite of Katalin knowing well that it is her brother who Alfred really loves.
