For the third time, the evil Wishmaster returns to wreck the lives of more innocents. This time, his victim is a beautiful, innocent and studious teenage girl named Diana Collins who accidentally opened up the Djinn's tomb (a strange box with a jewel inside) and released him. After gaining his freedom, the Djinn is asked by Professor Barash to let him be the one who makes the wishes. The professor wishes for two of the world's loveliest ladies to be in love with him.
