On a tiny star, two elderly Hammer Bros. are grandparents to a beautiful girl, Princess Peach. However, she is so beautiful, that the evil demon king Bowser decides to kidnap her and make her his wife. Mario, after hearing the story, decides to set off to free Peach from the demon king's claws.

A shooting star gives a couple the child they had wished for, Mario, but he is only an inch tall. As the child grows older, he becomes adventurous and eventually sets his sights on a distant city, convincing his Mama and Papa to let him journey there on his own.

The seven Mushroom Retainers play the seven dwarves, Mario plays the prince, Princess Peach plays Snow White, Bowser plays the evil queen, and Luigi plays the prince's brother in this retelling of Snow White, Mario style.
