When Mr. Esalat is looking for a topic for his TV show, he notices an advertisement in the newspaper about a missing girl. The picture of the missing girl is very familiar to him and he tries to remember where he saw it before. His wife Asieh is a teacher and at home she writes his mother's diary. When he searches for the address in that advertisement, he finds that it belongs to 30 years ago. Asieh is becoming interested in the missing girl too.

Before getting to the security office, the culprit is set up and left alone with his interrogator for an hour so that maybe they could get the information they need. That hour they spend together means something different to each of them and they both glimpse at their different stages of life in one day and live their lives backwards. The two men stroll in an unknown city and come to their young days. The time ends. The interrogator who’s been impressed by the culprit, tries to get him back to life and since he doesn’t succeed in doing so, he goes mad.
