In the gloriously hot summer of
1936
, a group of people meet at a country house party. Within three years, the country will be
engulfed in war
, but for now time stands still as they sip champagne on the lawn, engaging in casual flirtations and carefree conversation. Then a shocking
death
puts an end to their revelry, changing everything in an instant.
For all of them, that summer house party will be a turning point. The
mistakes
made during that fateful weekend will change their lives for ever.
