Solar-powered space aliens invade the earth, setting the planet's oceans on fire! The evil interlopers then barrage Atlantis with wave upon wave of flaming missiles. With Aqualad injured and out of commisison, it is up to Aquaman to save Atlantis and send the aliens back where they came from. Of course, the "Sea King" is aided and abetted by his many underwater friends, including an army of arthropods and dolphins who prove to be excellent volunteer firemen.
