During the last few days of his five-year prison sentence, galactic fugitive Gary Goodspeed accidentally rescues and befriends a seemingly harmless alien named Mooncake, who unbeknownst to him is one of the most powerful living weapons in the universe.
Before he can realize it, Gary becomes caught up in an intergalactic conspiracy led by brutal alien dictator, Lord Commander, who wants to use Mooncake's power to revert the universe to its natural state.
With no other choice, Gary and the misfit group of friends he made during his prison term become the last line of defense between Earth and the extinction of life as we know it.
