"The Stalker from Beyond!"
The Swamp Thing makes its way back to the swamp-bound laboratory where it was birthed, only to find that an extraterrestrial has set up shop in his old lab, trying desperately to repair its crashed space ship. The alien's arrival has been noted by others, as well, most importantly the government agency for whom Matt Cable works. He is called in to lead a group to investigate. Things get ugly, but more that one entity there has a conscience, and its not the humans.
