In this issue, Panthro is again an interloper and gets himself and the other 'Cats in trouble. This time, while off hunting for Rumpa, he stumbles onto an ancient graveyard. The spirits there don't appreciate him snooping around and try to kill him. He manages to fend them off, but he ends up breaking things in the process. This makes the spirits even more irate. After a fitful night's sleep, Panthro awakes and wonders if the graveyard incident was a dream. He realizes it was all too real when his friends fall ill thanks to the angry spirits. The only way to save his friends is to face off with the spirits once and for all. While he's gone, the Mutants attack the ailing ThunderCats - what a mess!
