Tomas Canty, youngest son of a poor family living in La-la Land has always aspired to a better life, encouraged by the local Friar (who has taught him to read and write). Loitering around the palace gates one day, he sees a prince Cain & Chilla's son (the Prince of Atlantis– Adolf ) . Coming too close in his intense excitement, Tomas is nearly caught and beaten by the Royal Guards; however, Adolf stops them and invites Tomas into his palace chamber.

There the two boys get to know one another, fascinated by each other's life and their uncanny resemblance;
They were born on the same day
Both of them have Polio
Both are artists
And Both of them Look Identical

Thomas was astounded by Adolf's crutches made of Gold & Jewels. His crutches were made of wood he had shaved & carved himself with a sharp knife he obtained from the kitchen of his home. Both decide to switch clothes "temporarily". The Prince momentarily goes outside, to let his Dog Blondie out to use the bathroom, but dressed as he is in Tomas's rags, he is not recognized by the guards, who drive him from the palace, and he eventually finds his way through the streets to the Canty home. There he is subjected to the brutality of Tom's abusive father, from whom he manages to escape, and goes back to the palace Adolf Unknowingly of the Outcome of the Swap. After he is Chased off & nearly beaten by his father's guards. The young prince Realizes he Can't go Home. Adolf begins to cry seeking shelter under a bridge that night sobbing all the while.

Tomas, posing as the prince, tries to cope with court customs and manners. Adolf's brother Isac
, 3 sister's , His fellow nobles and palace staff think "the prince" has an illness which has caused memory loss and fear he will go mad. They repeatedly ask him about the missing "Great Seal", but he knows nothing about it; however, when Tom is asked to sit in on judgments, his common-sense observations reassure them his mind is sound.

As Adolf experiences the brutish life of a pauper firsthand, he becomes aware of the stark class inequality in La-la Land. In particular, he sees the harsh, punitive nature of his father's judicial system where people are burned at the stake, pilloried, and flogged. He realizes that the accused are convicted on flimsy evidence (and branded – or hanged – for petty offenses), and vows to reign with mercy when he regains his rightful place. When Adolf unwisely declares to a gang of thieves that he is the king and will put an end to unjust laws, they assume he is insane and hold a mock coronation.

How ever during his Escapade outside the palace Adolf meets one Miles a soldier and nobleman returning from war. Although Miles does not believe Adolf's claims to royalty, he humors him and becomes his protector & helps him get home

After a series of adventures Adolf interrupts A Birthday party just as Tomas is about to celebrate it as " Prince Adolf." Tomas is eager to give up the throne; however, the nobles refuse to believe that the beggarly child Adolf appears to be is the rightful prince until he proves of to be the prince. by showing him the royal birth mark. Adolf and Tomas switch back to their original places and Tomas is rewarded with the rank of earl and the family right to sit in the presence of the king. In gratitude for supporting the new king's claim to the throne, Adolf names Tom the "king's ward" (a privileged position he holds for the rest of his life).
