The infant son of a wizard is swapped with a baby from our world. The later brings technology to the fantasy world, while the former finds his way home through magic. Naturally the two go to war over a woman. Some fantastic scenes including the invention of a paddle wheel, the awakening of a dragon, and the reassembly of a broken magic staff. A unique magic concept is used in which magic is visualized as linking strands of various colors visible only to the wizard and with different properties based on their different colors.
