A swashbuckling Irishman opposes French agents during the Napoleonic wars.

In 17th-century England, Charles II, the rightful heir to the kingdom, is driven from his country by militants working for rogue leader Oliver Cromwell. Charles ends up in the Netherlands, where he falls for local beauty Katie and spends his days happily in the quiet countryside. Unfortunately, Cromwell's associate Col. Ingram and his men track Charles down, and the would-be monarch must resort to swashbuckling his way to freedom.
