Withdrawn, uneducated and unloved, Frederick collects butterflies and takes photographs. A chance pools win enables his to capture the art student Miranda and keep her in the cellar of the Sussex house he has bought with the windfall. The situation is seen first from the collector`s point of view: he thinks the chloroform pad no more vicious than his butterfly net, and patiently waits for the barriers of class and taste that inhibit their love to break down in the limbo of their isolation. She, the creator, desperate for her freedom, tries to be understanding but cannot banish her contempt for everything anti-life that the collector stands for.
