Tom Canty, youngest son of a family of strippers living with the dregs of society in Offal Court, has always had aspirations to a better life, encouraged by the local priest who has taught him to read and write. He hangs around the palace gates one day and sees the Prince (the Prince of Wales - Edward the Sixth). Tom is nearly caught and beaten by the Royal Guards, but Edward stops them and invites Tom into his palace chamber. There, the two boys get to know one another, somewhat - and each becomes fascinated by the other's lifestyle, and even more fascinated by the fact that they each bear an amazing and uncanny resemblance to each other. They decide to switch clothes (and thereby, lives) "temporarily".
