A tiger escaped from the zoo. It was winter, and it had nowhere to go.

One winter day, a tiger escapes from the zoo. Gyeong-yu, who has been living off of his girlfriend, is suddenly abandoned by her for reasons he can't understand. Having nowhere to go, Gyeong-yu finds himself on the street with a suitcase. With the whereabouts of the tiger unknown, the people are gripped by a vague fear. Gyeong-yu, working for a designated driver service, drifts this way and that, and happens to come across his former girlfriend Yoo-jung. Yoo-jung has become a novelist, as Gyeong-yu once dreamed of doing. It seems they start over. However being in a tailspin, Yoo-jung is unable to write, and proposes Gyeong-yu a weird offer.
