Following the events of The LEGO Movie, Emmet, Wyldstyle, Unikitty, Benny and MetalBeard reunite to go to Legoland. However, they instead receive an invitation to go to a knock-off called Brick World. They then meet Risky Business, Lord Business' older brother, who tries to hypnotise them to perform in a Lego Movie live show. MetalBeard, Unikitty and Benny quickly go to their attractions, while Emmet goes with Wyldstyle to his. Emmet is unhappy, so Wyldstyle takes him to her attraction to cheer him up.
Because of the extent, the group end up enjoying Brick World; Business takes advantage and sends his robots to hypnotise them with VIP wristbands. Emmet and Wyldstyle evade being hypnotised and discover Business' evil plans, as well as the audience. With the help of the audience, Emmet and Wyldstyle build a lemonade stand mech and save their friends. Business tries to escape, but a policeman stopped Risky from this, arresting him for making Brick World without permission. Emmet and Wyldstyle thank the audience before finally heading to Legoland with their friends
