Hayakawa is a loose cannon as a cop, much to the annoyance of his department. One day after chasing a fleeing suspect who collides with a hurrying doctor during the arrest, Hayakawa helps the doctor to a patient about to deliver, only to find out it's a dog. The runt of litter is stillborn, but Hayakawa coaxes the little albino puppy back to life. Several months later Hayakawa is surprised by a transfer to the K-9 division, which he sees as punishment until the dog he's assigned turns out to be the German Shepard he once saved.
