The video shows a man surfing on a large wave in the ocean. The wave is so big that it creates a tunnel-like effect, and the surfer is seen riding inside this tunnel. The surfer is wearing a red and white wetsuit and is riding a white surfboard. The water is a deep blue color, and the wave is a darker shade of blue with white foam at the top. The surfer is seen carving through the wave, and the camera follows him as he rides along the wave.
