In the video, there are three children sitting on the floor in a hallway. They are all wearing matching pajamas. The boy is standing up and talking to the camera, while the two girls are sitting and looking at the camera. The boy then walks away, and the girls follow him. They all run down the hallway together, laughing and having fun. The hallway is well-lit, and there are doors on both sides. The children seem to be enjoying themselves and having a good time.
