When all of Gotham's animals start getting agitated at the same time, Terry and Bruce Wayne figure out that sound frequencies beyond human hearing are to blame. That points to one man: Shriek. The animals prove to be the tip of the iceberg when people suddenly lose the ability to understand each other's speech. Shriek eventually turns off the interference, but makes a demand of Commissioner Gordon: the city's safety for Batman's life.
