Synopsis:
Matt Hagen escapes from jail and returns to the magic pool which gives him the power of Clay-Face. Batman searches for the crook, but Clay-Face manages to escape. The villain seeks to extend the 48-hour time period that his power lasts by taking protoplasm from the pool to Professor Colton and forces the scientist to do experiments.

While the professor does his work, Hagen robs members of the Pharoah Club by impersonating the robbery victims. Batman catches on and uncovers Clay-Face’s new identity, John Royce. Using a freeze-ray powered by the protoplasm from Colton’s lab, Batman is able to neutralize Hagen and return him to prison.
