The play's focus is Southerner Regina Hubbard Giddens, who struggles for wealth and freedom within the confines of an early 20th-century society where fathers considered only sons as their legal heirs. As a result of this practice, while her two avaricious brothers Benjamin and Oscar have wielded the family inheritance into two independently substantial fortunes, she's had to rely upon her manipulation of her cautious, timid, browbeaten husband, Horace. He's no businessman, just her financial support; although he's pliable enough for her ambition, that ambition has driven him into becoming merely the tool of her insatiable greed. He uses a wheelchair.
Her brother Oscar married Birdie, his much-maligned alcoholic wife, solely to acquire her family's plantation and cotton fields. Oscar now wants to join forces with his brother, Benjamin, to construct a cotton mill. They need an additional $75,000 and approach Regina, asking her to invest in the project. Oscar initially proposes marriage between his son Leo and Regina's daughter Alexandra—first cousins—as a means of getting Horace's money, but Horace and Alexandra are repulsed by the suggestion, as is Birdie. Horace refuses when Regina asks him outright for the money, so Leo, a bank teller, is pressured into stealing Horace's railroad bonds from the bank's safe deposit box.
Horace, after discovering this, tells Regina he is going to change his will in favor of their daughter, and also will claim he gave Leo the bonds as a loan, thereby cutting Regina out of the deal completely. When he has a heart attack during this chat, she makes no effort to help him. He dies within hours, without anyone knowing his plan and before changing his will. This leaves Regina free to blackmail her brothers by threatening to report Leo's theft unless they give her 75% ownership in the cotton mill (it is, in Regina's mind, a fair exchange for the stolen bonds). The price Regina ultimately pays for her evil deeds is the loss of her daughter Alexandra's love and respect. Regina's actions cause Alexandra to finally understand the importance of not idly watching people do evil. She tells Regina she will not watch her be "one who eats the earth," and abandons her. Having let her husband die, alienated her brothers, and driven away by her only child, Regina is left wealthy but completely alone.
