A woman and her son are the only remaining colonists on a remote planet called Arcadus, where they are repeatedly terrorized by a half-goat, half-man creature called Pangor. Buck and Twiki visit the planet during an asteroid survey, and immediately after landing, Buck is attacked by a wolf-like creature native to the planet. Buck meets Syra and her son Delph, but at first they don’t tell him anything about Pangor. Buck finds out soon enough, however, when Pangor attacks the shuttle, damaging Twiki. Buck offers to take Syra and Delph away from Arcadus, but Syra refuses to leave, despite Pangor’s continued attacks. Buck disrupts Pangor’s next attack, but the satyr bites him during the ensuing fight; believing that he’s drowned Pangor, Buck returns to Syra’s house for medical treatment. Even now, Buck finds the Syra won’t leave – in fact, she’s mourning at the news that Pangor may be dead. Syra finally reveals the truth: Pangor was once known as Major Jason Samos, Earth colonist, and transformed into a satyr mere hours after becoming infected by something on Arcadus. But Buck is about to find out for himself that the infection came from a satyr bite…
