The ostensibly calm and courteous Gerald Ballantyne lives in and embodies modern suburbia. But he is haunted by the memory of a recent car crash and hounded by his estranged wife and her demands for divorce. Slowly, a festering insanity takes over and unwilling to face the outside world he embarks on a lunatic experiment. Confining himself to his middle-class home, he eschews contact with others and survives entirely off 'food' which he can find in his house. Based on JG Ballard's The Enormous Space.
