In a flash of light, Will-O'-the-Wisp is back! And once again he needs assistance from the Spectacular Spider-Man! But this web-slinger (aka Ben Reilly) doesn't know the Wisp! Because it was Peter Parker who first clashed with him in Amazing Spider-Man 167. Nevertheless inside the Iron Rock maximum security installation, the wall-crawler helps the Wisp break free from Dr. Jonas Harrow's control! However there's an even greater threat inside Iron Rock that neither Spider-Man nor the Wisp knows about! One that breathes fire!
