Synopsis:
A criminal, Burt Langdon, has stolen a museum artifact, the Horn of Herix. The Challengers, who have battled Langdon before, investigate and learn that Langdon is seeking the legendary weapon, the Doom Box.

Following a map the Challengers locate an entrance to a secret valley where the Doom Box is hidden. The path is guarded with many traps, but the Challs overcome each. They locate the missing horn along the trail, apparently left behind by Langdon.

When the Challs finally locate the Doom Box, the final trap is defeated by blowing the horn. Langdon and his men then appear, snatching the weapon from the heroes. The weapon is defeated and ultimately destroyed when Ace blows the horn again.
