Avant-garde composer Albert Sanger lives in a ramshackle chalet in the Swiss Alps, surrounded by his ` Circus` of assorted children, admirers & a slatternly mistress. The family & their home life may be chaotic, but visitors fall into an enchantment, & the claims of respectable life or upbringing fall away. When Sanger dies, his Circus must break up & each find a more conventional way of life. But fourteen-year-old Teresa is already deeply in love: for her, the outside world holds nothing but tragedy.
