Synopsis:
A plane carrying Matt Cable and Abigail Arcane crashes in the Scottish moors. Swamp Thing saves their lives by stopping the plane's momentum. Matt, Abby, and the pilot are pulled from the wreckage by Angus and Jenna MacCobb. The three humans are brought back to their house to recover. When the pilot attempts to return to the plane, he is killed by a werewolf.

Angus and Jenna then drug Matt and Abby. Their son is the werewolf. They used lights to fake a landing strip which caused the plane crash. They intend to use the blood of their captives to free their son of the werewolf curse and transfer it to the prisoners. Swamp Thing interrupts the proceeding, frees Matt and Abby, and slays the werewolf. Despite the monster's benevolent actions, Matt still blames Swamp Thing for the death of Alec and Linda Holland and vows to track it down.
