Two strangers meet by chance and one proposes an unthinkable bargain: each will commit a murder on the other's behalf so neither will have an obvious motive. The encounter binds their lives into suspicion and blackmail, creating a psychological contest of guilt, plausibility, and escalating consequences.

A young woman in the early 1950s experiences an increasingly severe depression while navigating academic opportunity, social expectations, and the pressures of adulthood. The novel presents her interior perspective as she struggles with identity, career choices, and the medical responses to her mental illness.
