Here’s a brief plot synopsis:
Bill Krang has a special gift: he can hear insects speaking. Although they incessantly hum the same nonsensical phrase ad nauseam, he can’t help but think there must be some reason he alone can hear it.
Now in his thirties, Krang’s body is beginning to literally collapse in places, just as he discovers there may be other hearers of the constant hum.
Convinced this is no coincidence, he sets out for answers, and manages to dismantle all he ever thought he knew about everything.
