Synopsis:
Scientists find a caveman frozen in ice. The ice melts and the man-beast is released, having been in suspended animation. Batman and Robin capture him with assistance from Batwoman.

Later, the beast escapes from the lab, killing Professor Lacy. Batman tracks the beast and uncovers a plot by the lab assistant to steal museum artifacts. The assistant, Harbin, is Lacy’s actual killer. The beast perishes saving Batwoman’s life, and Batman stops Harbin.
