The Exile (1980)

Based on a traditional African tale. A king has the habit whilst walking in disguise on the streets of his kingdom to listen to the wishes of his own people. One day he overhears two brothers daydreaming out loud about marrying the king's daughters, even if that meant being beheaded one year later. The weddings take place and one of the brother is decapitated one year later. The other one escapes execution at his wife's insistence. On a long journey full of surprising incidents, our hero himself becomes king of a village with wives and subjects. However, his earlier promise haunts him, and in order to save his family he accepts to be sacrificed.
