The series "One Day" is a British comedy-drama adaptation of the novel of the same name by David Nicholls. Emma Morley and Dexter Mayhew are graduates of the same university. They meet in Edinburgh on July 15, 1988, at their graduation party and immediately feel a spark between them. But fate separates them the next day. However, it turns out that fate has a rather specific plan for this couple: they will have to meet again every subsequent year, but only on July 15.
