A group of people in swim caps are playing volleyball in an outdoor pool, surrounded by a spattering of onlookers,  and an upright digital scoreboard.   A yellow ball flies into the right side of the pool and the people in the pool swim and move it to the left side of the pool, while a man in all white tracks them from the side of the pool on a raised cement border.   A person in the front spikes the yellow ball against a blue goal and past a goal blocker in the pool.   A person on the far left of the pool throws the ball into the right side of the pool where all of the players swim to follow it.
