This musical is adapted from the novel "Don Quixote" by Spanish writer Cervantes, but it also extends and expands the plot of the original work, using "time travel" and "play within a play" The story is both real and imaginary, cleverly combining the adventures of Don Quixote and the thought process of Cervantes. This unique dramatic structure enables this artistic interpretation based on classic literature to break away from the limitations of the era and have rich practical significance.

The most famous song in the play is "The Impossible Dream". This piece has become a must-have piece for musical baritone. There are more than 40 recording versions around the world. Super famous people such as Elvis Presley and Domingo have performed this famous song.

The 19th century Spanish writer Cervantes and his servant were arrested for being accused of contempt of the church. In prison they were interrogated by prisoners who robbed them of all their belongings, including Cervantes' manuscript. In order to preserve the manuscript, he asked to perform his own play to defend himself, hoping to win their approval.

So Cervantes began to tell the story of the idealist Don Quixote: Alonso Quijana was a rich old man who thought about the true meaning of life day and night, but in the process of thinking, he discovered that He went crazy and thought he was the knight Don Quixote, trying to resurrect the medieval chivalry, so he started an adventure with his servant Sancho.

During the adventure, he mistook the windmill for a giant and fought with it to the death; mistook the hotel for a castle, and fell in love with Aldonza, the cook inside, convinced that she belonged to him. The princess Dulcinea. Aldonza, on the other hand, is accustomed to being instigated by others and regards Don Quixote's love as madness. At the same time, his niece Antonia and the housekeeper were worried about his situation for fear of harming their own interests, and Antonia's fiancé was also unhappy about the matter.

Antonia decided to ask a priest to provide mental therapy to Don Quixote. At the same time, Don Quixote confessed to Aldonza who questioned his purpose, saying that he was fighting for his impossible dream, and sang the famous song "The Impossible Dream".

After experiencing a series of adventures, Don Quixote, who had just been named the "Knight of the Sad Face" by the hotel manager, was besieged by the Mirror Knight. The Mirror Knight was actually Antonia's fiancé. The doctor pretends to be a doctor in order to cure Don Quixote's madness. The Mirror Knight asked Don Quixote to see reality clearly and return to the real world. Don Quixote finally recognized reality in the reflection of the mirror and fainted. The story comes to an end. In the real world, the religious court comes to the prison to interrogate the prisoners, and the show is interrupted.

The prisoner was very dissatisfied with the ending of the story and tried to burn the novel, so Cervantes decided to change the ending.

After many twists and turns, Don Quixote finally fell ill. After a long period of coma, he woke up. It seemed that the knight's adventure was caused by his madness, and he could no longer remember it at all. But at this time Aldonza broke in. She was moved by Don Quixote's persistence and decided to follow him to continue his adventure. With Aldonza's help, he recovered his memory of the knight's adventure and decided to go on another expedition. But he was so weak that he died in bed.

The story really ended. The prisoner was so shocked by the story that he gave up the torture of Cervantes. At this time, the court decided to interrogate Cervantes and his servant. The prisoners wished him good luck and sang The Impossible Dream together again as the finale of the story.
