David Freeman, a Professor of Philosophy about to reach fifty, is tired of life. His only desire now is to control the timing and manner of his death. His plans for 'self-deliverance', however, are disrupted by the earthly deman's of people around him. Alone at last he carries out his plan, but is saved by the college electrician. Returning from hospital, David hears news that may change his mind - yet ultimately the vagaries of chance would have it otherwise.
