The action takes place in the living room of the country villa Orpheus and Eurydice, resembling the salon of an illusionist; Despite the April sky and bright lighting, it becomes obvious to the audience that the room is dominated by mysterious charms, so that even familiar objects in it look suspicious. In the middle of the room is a pen with a white horse.
Orpheus stands at the table and works with the spiritualistic alphabet. Eurydice stoically expects her husband to finish communicating with the spirits through the horse, which answers Orpheus' questions with knocks that help him learn the truth. He refused to compose poems and glorify the god of the sun for the sake of obtaining some poetic crystals enclosed in the statements of the white horse, and thanks to this he once became famous throughout Greece.
Eurydice reminds Orpheus of Aglaonis, the leader of the Bacchanas (Eurydice herself was also one of them before marriage), who also tends to engage in spiritualism, Orpheus has an extreme hostility to Aglaonis, who drinks, confuses married women and prevents young girls from getting married. Aglaonis opposed the fact that Eurydice left the circle of bacchanals and became the wife of Orpheus. She promised someday to avenge him for having led Eurydice away from her. It is not the first time that Eurydice has been begging Orpheus to return to his former way of life, which he led until he accidentally met a horse and placed it in his house.
Orpheus disagrees with Eurydice and, in order to prove the importance of his studies, cites one phrase recently dictated to him by his horse: “Madame Eurydice will return from hell,” which he considers to be the height of poetic perfection and intends to submit to a poetry contest. Orpheus is convinced that this phrase will have the effect of an exploding bomb. He is not afraid of the rivalry of Aglaonis, who also takes part in a poetic contest and hates Orpheus, and therefore is capable of any vile trick against him. During a conversation with Eurydice, Orpheus falls into extreme irritability and punches the table, to which Eurydice notes that anger is not a reason to ruin everything around. Orpheus answers his wife that he himself does not react at all to the fact that she regularly smashes window panes, although she knows very well what she is doing so that Ertebiz, a glazier, comes to her. Eurydice asks her husband not to be so jealous that he personally breaks one of the glasses, likewise proving that he is far from jealousy and without a shadow of doubt gives Eurydice the opportunity to meet with Ertebiz once again, after which he leaves to apply for the competition.
Left alone with Eurydice, who came to her at the call of Orpheus Ertebiz expresses his regret over her husband's so unrestrained behavior and reports that he brought to Eurydice, as was agreed, a poisonous piece of sugar for the horse, whose presence in the house radically changed the nature of the relationship between Eurydice and Orpheus. Sugar passed through Ertebiz Aglaonis, in addition to poison for the horse and sent an envelope in which Eurydice should enclose a message addressed to her ex-girlfriend. Eurydice does not dare to feed the horse a poisoned piece of sugar herself and asks Ertebiz to do it, but the horse refuses to eat from his hands. Eurydice, meanwhile, sees Orpheus returning through the window, Ertebiz throws sugar on the table and stands on a chair in front of the window, pretending to measure the frame. Orpheus, as it turns out, returned home because he had forgotten his birth certificate: he takes out a chair from Ertebiz and, standing on it, looks for the document he needs on the top shelf of the bookcase. Ertebiz at this time, without any support, hangs in the air. Having found evidence, Orpheus again erects a chair under Ertebiz’s legs and, as if nothing had happened, leaves the house. After his departure, the amazed Eurydice asks Ertebiz to explain what happened to her and demands that he reveal to him his true identity. She claims that she no longer believes him, and goes to her room, after which she puts a letter prepared for her in the Aglaonis envelope, licks the edge of the envelope to seal it, but the glue is poisonous, and Eurydice, sensing the approach of death, calls Ertebiza and asks him to find and bring Orpheus to have time to see her husband before death.
After Ertebiz left, Death appears in a pink ball gown with his two assistants, Azrael and Raphael. Both assistants wear surgical gowns, masks and rubber gloves. Death, like them, also dresses over a ball gown in a bathrobe and puts on gloves. At her direction, Raphael takes sugar from the table and tries to feed his horses, but nothing comes of it. Death brings the matter to an end, and the horse, having moved to another world, disappears; Eurydice disappears, transferred by Death and her assistants to another world through a mirror. Orpheus, who returned home with Ertebiz, no longer finds Eurydice alive. He is ready for anything, if only to return his beloved wife from the kingdom of shadows. Ertebiz helps him, indicating that Death forgot rubber gloves on the table and will fulfill any desire of the one who will return them to her. Orpheus wears gloves and penetrates the other world through a mirror.
While Eurydice and Orpheus are not at home, the postman is knocking on the door, and since no one is opening him, he puts a letter under the door. Soon, a happy Orpheus emerges from the mirror and thanks Ertebiz for his advice. Following him, Eurydice appears from there. The horse’s prediction - “Madame Eurydice will return from hell” - will come true, but on one condition: Orpheus has no right to turn around and look at Eurydice. In this circumstance, Eurydice sees a positive side: Orpheus will never see how she is aging. All three sit down to dinner. Over lunch, a dispute erupts between Eurydice and Orpheus. Orpheus wants to leave the table, but stumbles and looks back at his wife; Eurydice disappears. Orpheus cannot in any way realize the irreparable nature of his loss. Looking around, he notices on the floor by the door an anonymous letter brought in his absence by the postman. The letter says that under the influence of Aglaonis, the jury found in the abbreviation of the phrase Orpheus sent to the contest an indecent word, and now the good half raised by Aglaonis is sent to Orpheus’s house, demanding his death and preparing to tear him to pieces. A fraction of the drums of the approaching bacchana is heard: Aglaonis waited for an hour of vengeance. Women throw stones at the window, the window breaks. Orpheus hangs from the balcony in the hope of appeasing the warriors. In the next instant, Orpheus’s head, already detached from the body, flies into the room. Eurydice emerges from the mirror and leads Orpheus into the mirror behind him in the mirror.
The living room includes a police commissioner and a court clerk. They demand an explanation of what happened here and where the body of the slain. Ertebiz informs them that the body of the murdered was torn to pieces and there was not a trace left of him. The commissioner claims that the Bacchantes saw Orpheus on the balcony, he was covered in blood and called for help. According to them, they would help him, but before their very eyes he fell dead from the balcony, and they could not prevent the tragedy. Servants of the law tell Ertebiz that now the whole city is excited by a mysterious crime, everyone has put on mourning for Orpheus and ask for some kind of bust of the poet for his glorification. Ertebiz points the commissar to Orpheus’s head and assures him that this is Orpheus’s bust of the hand of an unknown sculptor. The commissioner and the court secretary ask Ertebiz who he is and where he lives. Orpheus' head is responsible for him, and Ertebiz disappears in the mirror after Eurydice calling him. Surprised by the disappearance of the interrogated, the commissioner and court clerk leave.
The scenery rises, through the mirror Eurydice and Orpheus enter the stage; Ertebiz leads them. They are going to sit at the table and finally have lunch, but first they say a thank-you prayer to the Lord, who determined their home, their hearth as their only paradise and opened the gates of this paradise for them; because the Lord sent Ertebiz, their guardian angel, to him, for saving Eurydice, who killed the devil in the shape of a horse in the name of love, and saving Orpheus, because Orpheus worships poetry, and poetry is God.
