A simple guy Zhenya works as an accountant and cannot admit to his colleague Alisa that he is in love with her. All Zhenya wants is to be with his beloved. Real magic happens: the witch-boss turns Zhenya into a terrier named Zheka, and he becomes Alisa's pet.
The guy's wish comes true, but Zhenya loses his human appearance: now he is a Jack Russell Terrier, which Alisa takes home. They wake up together, go for walks and fight off numerous admirers - in a word, an ideal life. Zheka even thinks about staying a dog. However, during the next full moon, Alice is in danger, so they urgently need to find a way to turn back into Zhenya.
