Two friends spend one night together after graduation, then let a single date each year mark everything that happens to them next. "One Day" follows that yearly check-in across two decades.
What is One Day about?
Emma Morley and Dexter Mayhew cross paths on the night of their university graduation in Edinburgh, and instead of becoming a couple right away, they become something harder to define. The series returns to the pair every July 15th for the next twenty years, catching them in different cities, different jobs, and different relationships, while the pull between them never quite disappears. Emma works through disappointing jobs and half-finished ambitions while trying to write; Dexter chases a television career that gives him fame before it gives him anything worth having. Friends marry, drift, and reconnect around them, and the show uses that single repeated date as a way of measuring how much two people can change without ever fully letting go of each other. It is a slow, patient structure that trades plot twists for the accumulation of small, telling moments.
Cast & crew
Ambika Mod plays Emma with a dry, guarded wit that softens gradually across the two-decade timeline, while Leo Woodall gives Dexter a charm that curdles into something more brittle as his choices catch up with him. Supporting turns from Eleanor Tomlinson and Essie Davis fill out the wider circle of friends and family who anchor the pair to real consequences.
Context & significance
Based on David Nicholls' 2009 novel of the same name, the series revisits material that was already adapted as a 2011 feature film, this time with room to slow down and give each year its own texture. The 2024 production drew strong response for leaning into the book's structure rather than compressing it, letting minor characters and quieter years breathe.
Where & how to watch
"One Day" is available to watch on K-Time with a free account login, with both Persian dubbing and Persian subtitles included so the show's dialogue-heavy pacing comes through clearly for Farsi-speaking viewers. The K-Time interface itself is built around a Farsi-first experience, so browsing, searching, and resuming an episode all happen in Persian by default.
