This time Tottori is treating a ferret that swallowed plastic. The same thing happened again, but the "monster owner" was being lectured by the vet and learned her lesson. Also, Tottori helps to cure the pet of the minister's granddaughter. The largest chain of animal hospitals was asked to take care of it, but they made a mistake and begged the vet to help. Somehow, it seems that Tottori has an enemy that tries to cause him problems.
