The video shows a first-person view of a person swimming underwater in a video game. The person is holding a knife in their right hand and is swimming through the water, passing by rocks and plants. The water is clear and blue, and the plants are green. The person is moving deeper into the water, as indicated by the depth meter on the screen, which shows that the person is at 41 meters, then 38 meters, and continues to go deeper. The person eventually comes across a large blue dinosaur and attacks it with the knife. The dinosaur is defeated and drops a blue egg. The person then picks up the egg and continues swimming.
