Kidnapped (movie, 1995)

When Scottish young gentleman David Balfour's father dies, he leaves school to collect his inheritance from uncle Ebenezer, who in turn sells the boy as a future slave to a pirate ship. When staunch Stuart dynasty supporter Alan Breck Stewart accidentally boards the ship, he takes David along on his escape back to Edinburgh. They part and meet again repeatedly, mutually helpful against the Redcoats and respectful, although David is loyal to the English crown, but learns about its cruel oppression. Both ultimately face their adversaries.
