With the sinister General Xelic and his evil army of Reptoids planning to attack Earth, Roswell must team up with a quirky group of other-worldly beings: a Mantis with a fear of germs, a Cyborg programmed to take everything literally, a telepathic Pleiadean, two bickering Grays, and an overly confident Fungarian.
