Cambridge, 1994.

Professor Don Lamb is a revered art historian at the height of his powers, consumed by the book he is writing about the skies of the Venetian master Tiepolo. However, his academic brilliance belies a deep inexperience of life and love.

When an explosive piece of contemporary art is installed on the lawn of his college, it sets in motion Don's abrupt departure from Cambridge to take up a role at a south London museum.

There he befriends Ben, a young artist who draws him into the anarchic 1990s British art scene and the nightlife of Soho.

Over the course of one long, hot summer, Don glimpses a liberating new existence. But his epiphany is also a moment of self-reckoning, as his oldest friendship - and his own unexamined past - are revealed to him in a devastating new light.

As Don's life unravels, he suffers a fall from grace that that shatters his world into pieces.
