While Hugo (10) enjoys a relaxing bubble bath in his tub, things start to get a little strange. Suddenly, the sounds around him no longer match what he’s used to.

Confused, Hugo ventures out of the tub, only to discover that this unusual auditory experience extends beyond the bathroom and throughout Mexico City.
