Inferno: From The Divine Comedy recap

Lost in a dark wood, Dante is met by the Roman poet Virgil, sent by Beatrice to guide him. They enter Hell and descend through circles arranged by kinds of sin: the uncommitted wait outside; the virtuous pagans inhabit Limbo; the incontinent are driven by storms, rain, mire, and conflict; heretics occupy fiery tombs; the violent suffer in blood, burning waste, and a forest of suicides; and fraud is punished across ten trenches. Dante speaks with figures including Francesca, Farinata, Piero delle Vigne, Brunetto Latini, Ulysses, and Guido da Montefeltro, learning how desire, politics, pride, and calculated deception shaped their ends. Below the giants lies the frozen circle of treachery, where Count Ugolino tells of starvation in a locked tower. At the center Lucifer chews Judas, Brutus, and Cassius. Virgil leads Dante down Lucifer's body past the earth's center, then upward through a tunnel until they emerge beneath the stars.

Dante finds himself lost in a dark wood and unable to reach a sunlit hill because a leopard, lion, and she-wolf block his way. The shade of the Roman poet Virgil appears and explains that Dante must take another road through the afterlife. In the next canto Dante loses confidence, but Virgil tells him that Beatrice came from Heaven to request his rescue, supported by Saint Lucy and the Virgin Mary. Reassured, Dante follows him through Hell's gate. They first encounter the souls who refused every moral commitment, then reach the Acheron, where Charon ferries the damned. A violent tremor and flash cause Dante to lose consciousness before the crossing.

Guided by Virgil, Dante has entered Hell after learning that Beatrice arranged his rescue. Beyond the uncommitted and the Acheron, he wakes in Limbo, home to unbaptized souls and virtuous pagans, where he is welcomed for a time among the great classical poets. Minos then assigns the damned to their circles. Among the lustful, blown endlessly in a storm, Francesca describes the love that joined her to Paolo and led to their deaths. Dante next sees the gluttonous under filthy rain, speaks with the Florentine Ciacco about factional conflict, and passes the avaricious and prodigal. At the marsh of Styx, the wrathful fight on its surface while the sullen lie beneath it. Phlegyas carries the travelers across, and Dante confronts Filippo Argenti. The fallen angels bar the gates of Dis, but a heavenly messenger opens them, revealing fields of burning tombs where the journey into lower Hell continues.

Dante and Virgil have passed through the upper circles and entered the city of Dis. In the fiery tombs of the heretics, Dante speaks with the proud Florentine leader Farinata and with Cavalcante de' Cavalcanti, whose misunderstanding about his son exposes the limited way the damned perceive time. Virgil then explains lower Hell's order: violence lies below them, while fraud and treachery occupy the deepest circles. A centaur escorts the pair beside a river of boiling blood containing tyrants and murderers. In the forest of the suicides, Dante breaks a branch and hears the imprisoned soul of Piero delle Vigne, while wasteful souls are chased through the trees. The travelers emerge onto a burning desert under falling fire. There Dante meets the defiant blasphemer Capaneus, and Virgil explains the source of Hell's rivers through the image of the Old Man of Crete.

After crossing the circles of incontinence and heresy, Dante and Virgil have entered the realm of violence. On the burning sand Dante meets his former teacher Brunetto Latini and three other prominent Florentines, all running beneath the rain of fire. At the brink, the monster Geryon carries the travelers down into Malebolge, the eighth circle, whose ten trenches punish forms of deliberate fraud. Dante sees seducers and exploiters driven by demons, flatterers sunk in filth, and simonists planted headfirst in fiery holes; Pope Nicholas III mistakes Dante for a successor he expects to join him. The diviners and false prophets walk with their heads twisted backward, their distorted sight answering their effort to see illicitly into the future. Virgil corrects Dante's pity and identifies several of the shades before the travelers move toward the trench of corrupt officials.

Dante and Virgil continue through Malebolge after seeing fraud punished in successive trenches. Corrupt officials are submerged in boiling pitch and guarded by the Malebranche. Their captain, Malacoda, supplies an escort but deceives the travelers about the route; two demons later grapple and fall into the pitch, allowing Dante and Virgil to escape. They meet hypocrites burdened by gilded lead cloaks and pass the crucified Caiaphas. In the thieves' trench, Vanni Fucci gives Dante a hostile political prophecy, and human bodies and serpents undergo violent exchanges of form. The eighth trench holds fraudulent counselors inside moving flames. Ulysses, sharing a flame with Diomedes, recounts how his hunger for experience took him beyond the permitted boundary of the known world until a storm sank his ship within sight of a mountain.

Having crossed most of Malebolge, Dante hears Guido da Montefeltro explain how Pope Boniface VIII obtained his deceptive military advice with a false promise of advance absolution. The next trench contains those who caused division: their bodies are repeatedly cut open by a demon, and Dante speaks with several religious and political schismatics as well as Bertran de Born. The final trench holds falsifiers afflicted by disease, including alchemists, impersonators, counterfeiters, and liars. Master Adam quarrels with Sinon until Virgil rebukes Dante for lingering over their dispute. The poets then approach the central well, where immense giants rise like towers. Nimrod speaks incomprehensibly, and Ephialtes remains chained. At Virgil's request, the unbound giant Antaeus lifts both travelers and sets them down on the frozen lake of the ninth circle, where traitors are locked in ice.

Dante and Virgil cross the frozen ninth circle, where treachery rather than uncontrolled appetite receives Hell's deepest punishment. They move through regions for traitors to family and country, and Dante forces Bocca degli Abati to reveal his identity. Count Ugolino pauses from gnawing Archbishop Ruggieri's head to recount how Ruggieri imprisoned him with his sons and grandsons in a tower, where they starved. Farther on, traitors to guests lie face upward with tears frozen over their eyes; Fra Alberigo explains that some such souls fall to Hell before their bodies die. At the center of the lake stands the gigantic, three-faced Lucifer, whose wings generate the freezing wind and whose mouths chew Judas, Brutus, and Cassius. Virgil climbs down Lucifer with Dante and passes the earth's center, where their direction reverses. They ascend a hidden passage and finally emerge from Hell beneath the stars.

In the frozen ninth circle, Dante and Virgil cross regions reserved for traitors to kin, country, guests, and benefactors. Count Ugolino recounts his imprisonment and starvation with his children, while other souls remain locked in the ice. At the center stands Lucifer, a vast three-faced figure whose beating wings keep the lake frozen. His mouths chew Judas Iscariot, Brutus, and Cassius. Virgil waits for the proper moment, then climbs down Lucifer's shaggy body with Dante. On passing the center of the earth, their orientation reverses: what seemed a descent becomes a climb toward the opposite hemisphere. They follow a hidden natural passage upward for hours. The cantica ends when the travelers emerge from Hell beneath the night sky and see the stars, ready to begin the ascent of Mount Purgatory.
