At a secret government facility, lab specimen 19-GB a cat receives an experimental injection. Test animal 19-GB makes a daring escape to avoid dissection from the military base. After swimming across a river, the serum caused 19-GB to painfully polymorph into a dog howling at the moon. Fortunately for 19-GB, he became the same breed of dog the lab sent out to find him, allowing him to blend in with the search dogs. The pursuing soldiers call off the search, as the new dog watches with cat eyes.
