Thebes, birthplace of Dionysus, Pierre Brice in the role, born of Zeus and Semele, endures a brutal drought that fuels public discontent and religious tension. Tiresias, [Akim Tamiroff], the famed seer, lays the blame on the god’s anger and on Pentheus for doubting the divine, arguing that the king’s reluctance to honor Dionysus only deepens the crisis.
Manto, [Alessandra Panaro], daughter of Tiresias, offers water to a enigmatic stranger who replies with wine sacred to Dionysus, and she later shares with her friend Dirce, [Taina Elg], a pair of futures doomed by prophecy: Manto is destined to become a virgin sacred to Demeter, while Dirce, promised to Pentheus, longs for a life away from the court.
An omen, conveyed by a priest, channels the old stories through Agave, Semele’s sister and Pentheus’s mother. She reveals an ancient prophecy: Lacdanos, the son of Ino—Agave’s elder sister who had him kidnapped and raised as a servant to secure the throne for Pentheus—will wed a virgin sacred to Demeter, and their son will someday rule Thebes. The revelation unsettles every plan, as Lacdanos is cast as both threat and instrument of change. Raf Mattioli embodies Lacdanos, the figure at the center of the prophecy, whose true lineage challenges the royal order.
To forestall fate and calm the land, Pentheus [Alberto Lupo] orders the sacrifice of Manto to Demeter, hoping for a harvest to vindicate his rule and appease the people. Dirce pleads for mercy, but her appeal only confirms the pull of passion and fate that binds the world to the god’s coming presence. At Tiresias’s urging, Dirce drinks the sacred wine to Dionysus the night before the sacrifice and, with other women, makes her way to Mount Cithaeron, where she encounters the stranger who first gifted Manto the wine.
The next day, the stranger—Dionysus—stirs the crowd against Pentheus, and a miraculous lightning bolt freezes the hand of the priest who would have killed Manto. The youth of Thebes gather on Cithaeron to celebrate bacchanalia and to witness the union between Manto and Lacdanos, while the stranger’s true identity slowly unfolds. It becomes clear that Lacdanos is the cousin of Pentheus and the legitimate king, meaning he can marry Manto even though she has been consecrated to Demeter.
Pentheus moves to quell the rebellion, sending soldiers to the foothills of Cithaeron, where many rebels are captured. Yet the Stranger escapes and later returns to the palace, only to be imprisoned at the cliffs of Cithaeron. To soothe the unrest, he frees all prisoners except Manto and Lacdanos, deepening the sense that the old order is breaking apart. Dirce visits the chained figure, who reveals his divine identity and his impending departure from the mortal realm.
Meanwhile, Tiresias reveals to Polycrates (the leader of the tribe once beholden to Athamas) that Lacdanos is the true king of Thebes. The freed forces—led by Polycrates’s soldiers—join the Bacchae, clashing with Pentheus’s army in a fierce, fateful struggle. In the end, Lacdanos defeats Pentheus in a duel and ascends as the new king of Thebes, while Dionysus ascends to godhood and Dirce is poised to lead the Bacchae into a new era of power and ritual influence. The tale closes on a rebuilt, if uneasy, Thebes, where divine and mortal wills intertwine and prophecy gives way to a volatile, yet transformative, future.
