It’s the eve of Leonard’s departure for the Front and everything seems to be falling apart for the young couple. But despite their fears the world keeps turning, time keeps moving on, and over a period of sixty years the invisible bond between two people is stretched to its limit. 

From writer Nick Payne, (Tony Award-nominated Constellations; We Live In Time and Wanderlust, BBC/Netflix), One Day When We Were Young is a delicate, intimate, heart-breaking picture of two lives played out against an ever-changing world, and a glimpse of the fragility of the promises we make to one another.
