Gotham City, suffering yet again from sweltering temperatures and increased gang warfare, experiences more mysterious deaths. Aided now by his protégé, Robin (Tim Drake), Batman worries that this may be yet another series of hunts by the brutal Predator aliens, yet refuses to disclose this to his partner, irking Robin. Indeed, not one, but two beasts are prowling in Gotham: an elder creature who seems to tell stories of previous hunts to his younger partner.
