Buried for decades, the body of a young woman is found in the melting ice. A thousand miles and 45 years away… a crack forms in the crystal of a marriage. It's the week leading up to Kate and Geoff's wedding anniversary and preparations for the party are in full swing. As they choose the music for their first dance, a letter from Switzerland quietly shatters their world. Is the past another country? Or are the secrets in the attic of our memory destined to return? Adapted from Andrew Haigh's critically acclaimed 2015 film, 45 Years is an achingly tense, intimate and moving dance to the music of time.
