Dante travels through the circles of Hell and battle demons and other monsters, including Lucifer himself, in order to save his beloved Beatrice.
Returning from the Third Crusade, Dante arrives home to find his servants slain, his father dead and his beloved fiancée Beatrice dying of a stab wound to the stomach.
Attacked by demonic children, he and Virgil escape into a large building; they enter a hall of great rulers, philosophers, and thinkers.
He encounters Ciacco, a man from his village, who confesses to gluttony; Dante tells him to be free and blesses him with his cross.
Upon entering Violence and given passage through the Phlegethon by Nessus, Dante descends into the Forest of Suicides upon hearing a familiar cry, soon finding his mother growing from the sapling of a tree.
Beatrice attacks Dante, forcing him to look into the ninth circle of Treachery, where he sees his greatest sin: allowing her brother to take the blame for his slaughter of the heretic prisoners.
He rips off his tapestry, which then disintegrates and transforms into the Hebrew serpent, slithering away, as Lucifer laughs, implying that he is biding his time for revenge.
