Synopsis:
Batman and Robin trail gang leader, Vince Kenton to the waterfront. While looking for them, Batman is knocked into the water by a lightning bolt and is transformed into a water breather. He can only continue on land with the aid of a glass helmet filled with water.

When the Dynamic Duo face the crooks again, the helmet is shattered, allowing the crooks to escape. The next time they meet up, Batman passes out and the helmet is again broken. This time however, the strange water-breathing effect has worn off and he can breath air again. This surprises the crooks, allowing them to be caught.
