Baba Segi, a prosperous Ibadan man with three wives and seven children, marries Bolanle, a university graduate. When she fails to conceive, he takes her to a hospital, where the doctor finds that he himself is sterile. The older wives' children were fathered by other men, including the family driver Taju, and the secret they have guarded unravels, with deadly consequences inside the household.
When a husband's status depends on fertility he assumes is his, childlessness is always read as the wife's failure. Because his pride makes the truth unspeakable, the women take on the whole burden of fixing a problem they did not cause. They get children covertly, and the deception props up the very ego that made it necessary.
Each wife enters the marriage for a different transaction: to settle a family debt, to escape poverty or abuse, to gain security, or to find a hiding place from past trauma. Seen this way, the polygamous household is a set of bargains rather than romances. Each woman's behavior makes sense as protecting the terms of her own deal.
Rival wives compete for status and resources, but a shared, dangerous secret binds them into a coalition. A newcomer who is not in on the secret becomes a threat to all of them. An educated outsider whose presence draws in scrutiny, such as doctors and tests, can unite rivals in hostility, even to the point of violence.
