The episode begins on the moon during the reign of Moon Kingdom, ruled by Queen Serenity. However, the evil Queen Beryl unleashed the power of the Negaforce and attacked the Moon Kingdom and killed all of the Children of the Moon, including the Queen Serentity's subjects. She used the remainder of her powers to send her daughter, Princess Serena, her cat advisers, Luna, Artemis, and the rest of the Moon's inhabitants to an alternate future on Earth to be reborn, and kept their memories of the Moon Kingdom to herself, and Luna and Artemis were ordered by Queen Serenity to find Princess Serena, so she will, at last, be safe.

Meanwhile, Princess Serena, now, in a new identity, as just Serena, is late for school. On her way to school, she sees some cruel kids picking on a cat. After driving them away, she removes a bandage they put on the cat's head, revealing a crescent moon on her forehead. Luna senses something, suspecting that Serena might be "Sailor Moon".

At school, Miss Haruna tells Serena that she failed her exam with 30%. Melvin, the geek, got a 95%, which he was actually disappointed with. Serena and her friend Molly decide to go play the new Sailor V video game, and then go shopping at Molly's mother's store for earrings.

Meanwhile, inside the Negaverse, Queen Beryl makes plans to unleash the power of the Negaforce. To do so, she must have energy. She sends her commander, Jedite, to gather energy for the Negaforce. Jedite's servant, Morga, is disguised as Molly's mother and is selling the jewelry (charged with dark energy) at low prices. Serena and Molly are forced to sneak out of the store when a huge crowd tries to get a diamond that costs 10 dollars.

Serena crumples up her test and throws it away. It hits Darien in the head, and he calls her "Meatball Head". Meanwhile, Morga begins stealing energy from the girls at the store, and sending it to Jedite. Luna, tells Serena that she is Sailor Moon. She gives her a locket and tells her to use it to transform by repeating the phrase: "Moon Prism Power". After Serena transforms into Sailor Moon, Luna tells her Molly is in trouble and they leave.

Morga reveals her true identity to Molly, but Sailor Moon arrives to fight her. Morga sends her victims, who are now under her control, after Sailor Moon, but a mysterious masked man named Tuxedo Mask arrives. After Sailor Moon inadvertently some sort of sound-based attack to immobilize Morga and her slaves, Luna tells Sailor Moon to throw her tiara and say "Moon Tiara Magic". Sailor Moon uses Moon Tiara Magic and destroys Morga, returning the energy.
