The video begins with a single red cell floating in a dark space. The cell is round and has a shiny surface. As the video progresses, more red cells appear, and they begin to move and interact with each other. The cells are shown in various sizes and shapes, some appearing larger and more prominent, while others are smaller and more distant. The background remains consistently dark throughout the video, with small white specks that could be interpreted as stars. The red cells are the main focus of the video, and their movement and interaction with each other are the primary actions depicted.
