Errol Flynn duels into action in the spirited film of Mark Twain's classic novel. Amid 16th century England's pomp and poverty, two lookalike lads, one a beggar and one young Edward VI, exchange identities for a lark. But their switch backfires and it's up to soldier-of-fortune Miles Hendon (Flynn) to turn the tables on a conspirator (Claude Rains) and return the correct lad to assume the throne.
