Reports have been coming in of strange radiations from a planet one-thousand light-years away from Earth. It's weird radiation levels have been causing strange anomalies to occur on planets both near and far. Luckily for the universe, Voltron is here to investigate and, hopefully, find a way to help. Back on Earth, a squad of fliers was sent out to test some new ships. During the test, a meteor shower began. This was unlike anything Earth had experienced before. Some were glowing strange colors or were cold instead of hot. Some were seemingly teleporting. But they all had one thing in common. They all broke through Earth's atmosphere and crashed down on the fliers. Not one ship remained. Among the fallen was Shiro's ex-fiance, Adam. But what happens when Adam finds himself stranded on an alien planet, one-thousand light-years away from Earth covered in odd, bouncy, squishy creatures called slimes? And what's more, the radiation readings are the same as what have been reported to Voltron.
