Conan awakens inside a cage made from the bones of giants and finds he's being experimented upon by Raseri.

Meanwhile, Dake the freakmaster is on his way to the giant's village with his entourage of Penz the wolfman, Tro the catwoman, Sab the four-armed man, and Kreg his assistant.

Conan eventually escapes the cage in which he is being held and sets fire to Raseri's hut, sending all of his research on humans into flames.

The flaming hut distracts many of the giants and Dake is able to capture Teyle, as well as Morja and Oren, who are also Raseri's children.

As Conan escapes, the giants release their "Hellhounds", a massive beast with the appearance of a cross between a bear and a wolf.

Figuring that more of his own kind will attract too much attention, Raseri decides to leave the swamp to look for his children by asking the local humans if they have seen a man resembling Conan.

Fosull decides on a similar plan, but coats himself in mud (so as not to display his green skin) and follows the cart's tracks, knowing what they look like.

Raseri eventually finds Fosull's wagon and learns that the cart in front of him contains a Varg who is tracking their children.

Penz sprinkles a powder (stolen from Dake) that turns all liquid to water into the cups of the slaves while Raseri is not watching.

Fosull, whose drink was not sprinkled with the magical powder, kills Raseri with his poisoned spear and dies shortly afterwards.
