The video shows a group of people wearing scuba gear swimming in a large metal cage underwater. The cage appears to be made of metal bars and is quite large, allowing the divers to move around comfortably. The water is a deep blue color, indicating that the location is likely in the ocean. The divers are wearing wetsuits, flippers, and oxygen tanks, and they are using hand signals to communicate with each other. The sunlight is shining through the water, creating a beautiful and serene atmosphere.
