Linkara, snarky comic book reviewer and a Champion of his universe, plans to celebrate his birthday by watching bad movies with his fellow Channel Awesome contributors. However, his birthday plans are interrupted by Allen Park, his liaison with the U.S. government. Allen reveals that government has lost contact with the crew of the Caelestis spaceship during a manned mission to Jupiter and requests Linkara's help to find out what happened. With the help of his fellow critics, Linkara uses Comicron-1 to launch a rescue mission, but soon discovers a foe from his past that threatens to destroy everything he cherishes.
