Hard Hat Emmet
“Good morning, city!”
Every day, Emmet goes to work exactly by the steps in the instructions booklet that he always keeps in his hand. As part of Bricksburg’s busy construction crew, he helps to rebuild the city as briefed by President Business.
Emmet wants to be popular, but he struggles to stand out in the crowd. Even his fellow construction workers hardly know he’s there. But all of that is about to change, thanks to a mysterious stranger and a legendary Prophecy about the most special minifigure in the entire world!
