Written in Hewett's freewheeling epic style, The Chapel Perilous is a journey play that spans the period between the 1930s and the late 1960s. The story concerns Sally Banner, an over-reacher who attempts to find fulfilment – whether through her gift of poetic expression, through her sexual relationships, or in later years through political activism - and ultimately finds it through self-acceptance. Thematically the play contains the qualities and concerns which are often associated with Hewett's style – female sexuality, questioning of authority and morality, and anarchic tendencies towards structure in both dramatic text and social attitudes.
As Hewett remarks in her 1979 Hecate article: 'Sally is balanced by several symbolic female figures, the "Authority figures" of Headmistress, Anglican teaching "sister", and mother... [along with the] lesbian love figure, Judith, who stands for intellectual control and denial of sensual love' ('Creating Heroines in Australian Plays', p. 77).
