While she is hurrying to get to her school on time one day, Usagi Tsukino accidentally steps on a black cat. When she picks it up she notices a crescent shaped symbol on it's forehead. Usagi thinks that it's just a bald spot and runs off to school. Later that day, Usagi takes a nap, only to be awakened by the cat from earlier that day. To her surprise, the cat starts talking to her and introduces itself as Luna. Luna tells Usagi that she is destined to become a Sailor Soldier, and gives her a mystical brooch that enables her to transform into Sailor Moon by calling out Moon Prism Power! Make Up!
Usagi finds out that not only does she need to find the other Sailor Senshi, but she also has to find the Moon Princess and protect the supremely powerful Silver Crystal from the Dark Kingdom; a mysterious group of villains that attempt to steal life energy from humans to strengthen and revitalize their ruler Queen Metaria to dominate Earth and exact their vengeance on the people of the White Moon, who have been reborn and reincarnated as "ordinary" teenage girls on Earth.
Usagi eventually finds the other five Sailor Senshi-Sailor Mercury, Sailor Mars, Sailor Jupiter, and Sailor Venus- and finds out that Tuxedo Mask is actually Mamoru Chiba, a man that had previously made fun of her about multiple things, including her low test grades and her meatball-like hairstyle. He and Usagi later begin to fall in love with each other. However, during a battle with Kunzite, Tuxedo Mask injures himself while trying to protect Sailor Moon from an attack, causing him to lose consciousness as well. Sailor Moon is overwhelmed with sadness when this happens and after crying out in anguish, her tiara breaks, revealing a crescent moon symbol on her forehead and instantly transforms into Princess Serenity, the Princess of the Moon Kingdom, Silver Millennium. After regaining her memories of her past life, one of her teardrops reveals the vastly powerful, legendary Silver Crystal itself, which starts to send out immense healing energy throughout the city. After attempting to attack the newly awakened Serenity, Queen Beryl and Kunzite abduct an unconscious Tuxedo Mask.
To find answers, Luna takes the five Sailor Senshi to the Moon, where the ruins of Silver Millennium lie. The spirit of a young woman with silver hair appears before them and thanks Luna for bringing them here. She reveals to Sailor Moon that she is/was her mother in her past life, Queen Serenity. She explains that they all lived happily on the Moon with their beloved kingdom, the very first era of Silver Millennium. However, an evil entity from the cosmos, Queen Metalia, arrived out of the blue and brainwashed the humans of Earth to plan a major assault on the Moon Kingdom.
