At a reunion dinner are a number of graduates now in their early forties and mostly in responsible, influential positions. All starts smoothly with conventional greetings and old boy reminiscences. A slightly discordant note is struck by Snell, a man of such insignificance that everyone has forgotten him, and continues to forget him from one moment to the next. As the night goes on, the college port causes behaviour surprising in those in positions of political, academic or spiritual authority. Into the resulting bear garden stumbles Lady Driver, the Master's wife who is short sightedly searching for the lost love of her youth. The insignificant Snell sees in her the chance to make up for all the opportunities of undergraduate life he missed before.
