It's summer vacation, but two high schoolers have been instructed to clean the (empty) swimming pool. As they sweep the pool, they initially discuss school life, love and makeup. But it isn't long before their worries begin to overflow and their thoughts intersect.
Unfortunately the movie Swimming in a Sand Pool is not yet available on HBO Max.
