Synopsis: Burt Langdon has stolen the Horn of Herix from a museum. The Challengers track Langdon to a valley where a Doom Box, a legendary weapon, is hidden. Weird boobytraps slow the Challs: an alligator, a tree-turned-elevator, and giant robot Romans. They find the horn discarded, then the Doom Box guarded by a flames and a two-headed dragon! Ace blows the horn and a ray from the box drives back the dragon and flames. Langdon’s gang attacks, grabs the box, and runs. Ace blows the horn again, and the box explodes, because the horn was made to destroy the box if it were moved from its ring of flames.
