A person is filming themself underwater in a pool at night. The person is wearing a long-sleeved black shirt and light-colored pants. The pool is lit up with blue lights, and a building can be seen in the background. The person swims toward the edge of the pool, and then bobs back down. The lighting is bright enough to see clearly, but dark enough to create a sense of being in a quiet, private space.
