On an alien planet, Princess Wanda and her maid, Marcia, have been captured and imprisoned by the Mala the Yellow Queen. Spotting some yellow oil in their cell, Wanda gets an idea. They trick the Queen into entering their cell. Once the three women are alone, Wanda and Marcia ambush the Queen and tie her up. Wanda puts on the Queen's clothes, and she and Marcia both cover their bodies in yellow oil so they can pass as alien women. They fool the guards and escape.
Soon after, the real Queen Mala is discovered bound and gagged in the cell by her servants. She has been dressed in Wanda's clothes, because this was the 1930s.
