15 juli 1988. Na één dag samen te hebben doorgebracht, ontstaat er tussen de tegenpolen Emma Morley en Dexter Mayhew een vriendschap voor het leven. Twee decennia lang kijken we op 15 juli hoe het met Em en Dex gaat en hoe hun levens met elkaar verwikkeld zijn. Hun relatie verschuift in de loop der jaren, totdat ze zich op een bepaald punt in hun leven realiseren dat hetgeen waar ze naar zoeken en op hopen, dichterbij is dan ze al die tijd hebben gedacht.
