Taking place on a Caribbean island divided by social prejudice, âOnce On This Islandâ is a calypso-flavored re-telling of the traditional âLittle Mermaidâ tale. The show revolves around Ti Moune, a poor peasant girl, who falls in love with Daniel, an upper class boy whose life she saves after a car crash. Various gods control the peasantsâ lives including the god of Love, (Erzulie) Earth (Asaka), Water (Agwe), and Death (Papa Ge). The show focuses on the effects social class divisions have on love.
