Mr. Black Widow follows Rebecca Ruiz, a sharp actuarial investigator for Vanguard Mutual whose obsession with numbers uncovers a horrifying, hidden pattern. Buried across separate cities and causes of death lies a chilling rhythm: wealthy, accomplished women dying of seemingly "natural" medical events shortly after marriage—each leaving behind a silent $10 million insurance rider to a phantom husband who vanishes without a trace.
Driven by her late father’s principle that a policy is a promise, Rebecca sets out to prove the deaths are no coincidence. Realizing she is tracking a master manipulator who custom-builds untraceable medical histories for every victim, Rebecca races alongside law enforcement to piece together his trail before another courtship ends in tragedy.
