It begins when Mary Gibbs aka Boo was little. She played with her aunts Tilly and Milly. While they play they saw a commercial for Honker's Pizza Parlor. Not far away the young prince Michael is going on the trip with his parents, King Ted and Queen Isabella of Airderia to visit Boo's home. Boo realized that Michael is here and fall in love. But the storm took him away. King Ted and Queen Isabella realized that their son is missing and hope the lost prince will return.

14 years later, Boo still dreams of marrying the lost prince. When she went back to the monster's world, Boo realized that her best friends are celebrating her 18th birthday at Monsters, Inc.

Meanwhile, Fungus misses Randall. Then in jail, the CDA guarded Randall's cell only to realize he had turned invisible to escape.

Hours later the gang are still having a blast, Sulley invites his former fellow Oozma Kappas to that. But the party crashed and they turned to see Randall wearing the necklace that gave him shapeshifting powers. He blamed Mike Wasowski and Sullivan for putting him in jail. When the party was over, Mike and Sulley will protect Boo again if anything bad will happen to them.

He was delighted to see Boo again! he made a deal with Boo, if she does love the lost prince before the sun sets, all her dreams come true but if she doesn't, she will be his! So he erases Michael's memories and locked them in his necklace.

When Boo and Michael heard of the Blood Moon Ball coming to Monsters, Inc. they were invited. On their way to the Blood Moon Ball, Boo, Mike, Sulley, and Michael meet Sanders Sullivan, Sulley's grandfather who retired to Monstropolis Oasis and his assistant, Yeti who recently moved to Monstropolis. He taught Mike and Sulley a downward dog.

As Boo and Michael decided to hand out invitations to the ball. On their way, they stopped at a theme park called Pixar Planet which features computer-animated originals from Disney and Pixar. Boo and Michael see the wonders of the theme park only to discover Randall is behind them! Boo goes through the princess's room and discovers she's a princess too.

When they arrive at the Blood Moon Ball, they stumble upon Roz who is dressed like a duchess. Johnny Worthington III arrived telling her he's Hercules. Then Sanders dressed as Carl Fredrickson appeared telling them about the good old days. Then Randall, dressed as an evil sorcerer, appeared telling Mike the joke(what is the most serious crime under the sea? Grand theft otter.) Everyone is having a blast. Mike challenges Art in the Mamushka dance. At dinner, Randall arrived with clowns and a behemoth and performed dark magic in front of the guests, which are surprised and excited and Randall agrees that the festival is that way. But midnight stroke and Boo lost a glass slipper but Michael placed it on her foot.

Meanwhile, Boo is trying to sing to the water and as the water takes her to Airderia, Boo sings about her prince and talks to the woodland animals.

Suddenly Randall saw Boo and decided to marry her himself! So he morphs himself into the evil man, Vincent. Macintosh Graves, who can turn invisible, spies on Randall and goes back to Mike to tell him Randall's evil scheme.

Later as Boo watched TV something is hypnotizing her. It was from Vincent. His plan is working.

A day later Terri and Terry Perry are walking when they saw the evil man looking in the mirror seeing his reflection. The conjoined monster brothers told Mike that Boo is forced to marry Randall in disguise so they think of ways to stop that wedding. Then they packed the horns and sounded the alarm. When the monster blew the small horn, they arrive to stop a disguised Randall from marrying Boo. Vincent thought that was funny, but when the monster blew the bighorn, the villain was outraged because Michael is behind this. Vincent screamed and saw his evil necklace falling to the ground and broke. All the memories returned to Michael's mind, Boo was no longer under his spell and Vincent sounded like Randall when he saw Boo and Michael being reunited.

As Michael revealed he is the lost prince to Boo, the sunsets and chains appeared on Boo's wrists. Laughing victoriously, Randall transformed back into his scaly lizard-like self and carried Boo and runs away with her.

Painter paints up an exact copy of the Excalibur. So Michael grabbed the Excalibur. Randall transforms himself into the Night Viper. Randall tried to stop Mike who discovers that Randall was his best friend. As Randall aimed his deadly bite at Boo, Michael stabbed him, causing Randall's skin to melt. With his painful scream, Randall fell to his death. As he fell, his body turned to ooze. The Excalibur then dissolved into Painter's chest so he could make more paintings when needed. When Boo's 13 Princess friends found out that Sulley is in danger they saved the day by using their skills and made a dress parachute. Sulley who wore Rapunzel's dress landed in the mattress on top of the mattress store in downtown Monstropolis and is kissed by Fiona using her father in frog form. Sulley is grateful to them.

When Michael and Boo were married. They have a reception at Honker's Pizza Parlor and rode off to their happy ending. The movie ends with a painter jumping up at the screen before saying "That's all folks!"
