Synopsis:
Klag, a cro-magnon caveman, falls into a cave during a confrontation with his enemy Brugg. Ice and minerals preserve Klag, until an earthquake frees him centuries later. The minerals also give Klag strange powers. The caveman leaves the cave in search of Brugg, his enemy.

Klag finds a man who resembles Brugg in the jungle. He attacks, then learns that the man is not his foe. Klag continues the search in Gotham City, where he believes Batman to be Brugg. Batman and Klag battle, until Klag unmasks the Caped Crusader. He realizes that Batman is not Brugg and continues his search elsewhere. Batman and Robin pursue the caveman and use a plastic sealant to trap him. Once Klag has been subdued, he is turned over to scientists for study.
