Setting and principal figures
The action moves between early‑20th‑century England and New York’s theatrical world. Central figures are Jill Mariner (young, recently dispossessed), Sir Derek Underhill (her erstwhile fiancé), Lady Underhill (domineering mother), Freddie Rooke (amiable friend), Major Christopher “Uncle Chris” Selby (resourceful, morally ambiguous guardian), Wallace “Wally” Mason (writer and eventual suitor), and the theatrical syndicate around Otis Pilkington, Roland Trevis, Isaac “Ike” Goble and associates. Secondary players include chorus members (Nelly Bryant, Mae D’Arcy, Babe, the Cherub), social acquaintances (Mrs Waddesleigh Peagrim, Ronny Devereux, Algy Martyn) and American connections (Uncle Elmer Mariner).

Chronology and causal developments
The domestic episodes in England establish the pressures that propel Jill abroad. Early incidents—Jill’s public arrest for intervening in cruelty to a parrot, Freddie’s convivial loyalty, and Lady Underhill’s social disdain—intensify when Lady Underhill arrives from the Riviera and disapproves Jill’s social origins. Under maternal and public pressure Derek breaks the engagement. Simultaneously Jill’s finances collapse after speculative losses and Uncle Chris’s squandering of trust funds; deprived of support, Jill leaves for America with Uncle Chris.

In England a theatrical catastrophe—the Leicester Theatre fire during a poorly received first night—functions as both literal evacuation and symbolic transition. Wally and Freddie intersect with Jill around these episodes; the stage and its disasters foreshadow the centrality of theatre to Jill’s reintegration.

New York: labour, production, and negotiations
Arriving in New York with limited means, Jill obtains chorus work in a new musical, The Rose of America, produced by Pilkington with Trevis composing and Goble managing. The text traces industry practices (rehearsal routines, managerial abrasiveness, rewriting of books) and social navigation: Uncle Chris contrives modest lodgings and networks among wealthy patrons to replenish Jill’s position; Freddie contemplates and then begins transatlantic action to assist.

Production crises crystallize and reconfigure relationships. Management dismisses Mae D’Arcy; Jill leads a chorus strike, and Wally publicly supports the girls while rewriting Pilkington’s satirical book into broader comic material—reshaping roles (notably Freddie’s) and improving the show’s prospects. A contentious financial episode follows: Uncle Chris facilitates a transfer of ten thousand dollars that enables Jill to buy Pilkington’s interest; Pilkington accuses them of deceit, but Jill offers to return the property, defusing the dispute.

Resolution and thematic synthesis
The play ultimately opens successfully. Personal outcomes follow the theatrical triumph: Freddie becomes engaged to Nelly; Jill attains emotional clarity and accepts Wally’s proposal; Derek is left humiliated and isolated. The narrative consistently links public reputation, class anxieties and economic necessity to private attachments: Lady Underhill’s status consciousness, Uncle Chris’s opportunism, Freddie’s loyalty and Jill’s pragmatic agency operate within a commodified, performative social world. Theatre is depicted both as refuge and instrument for social mobility, while ethical ambiguity and practical solidarity drive the final realignment of relationships.
