Three boys stand in a classroom with a green chalkboard and a white projector screen; the boy in the center, wearing a gray t-shirt, performs a dance routine, moving his arms and legs rhythmically, while the boy on the left, in a purple shirt, crouches and then stands, and the boy on the right, in a red hoodie, holds a paper and watches, as a girl in a light green shirt enters from the right and begins to dance.
