Anna perishes of dehydration during a planetary heatwave after her scheming stepfamily and treacherous fiancé rob her of food and shelter. Opening her eyes seventy-two hours before the catastrophe begins, she liquidates her entire equity portfolio into cash. Using an enchanted spatial ring with infinite storage capacity, Anna stockpiles mountains of chilled provisions, medicine, and defensive armaments inside a reinforced sanctuary.
When blazing temperatures scorch the city, Anna relaxes in air-conditioned luxury while her former tormentors starve on the melting asphalt below.

As a secondary plague strikes and her reborn ex-fiancé peddles tainted cures, Anna must deploy her stockpiles to defend her sanctuary and crush his ambitions.
