After being named emperor, Caligula takes power and soon finds himself caught between his desire for freedom and the inevitable corruptions of power. In his quest to break away from the moral constraints of Roman society, he begins to unleash a wave of brutality and excess that shakes the empire.
As he immerses himself in a world of lust, betrayal, and unchecked ambition, Caligula surrounds himself with fascinating and disturbing figures, such as his lover, Caesonia, and his most loyal friend, the philosopher Macro, who attempts to guide him through the palace intrigues. However, madness and paranoia begin to consume Caligula, plunging his reign into an abyss of chaos and violence.

As he faces conspiracies and distrust, the emperor is forced to confront the consequences of his own depravity. In an exciting and tragic climax, his reign becomes a chilling reflection of the dangers of absolutism, leaving an indelible mark on the history of Rome.
