Caroline Baker is having a day like no other.
While playing hooky from her job as an independent soybean trader at the Chicago Board of Trade, she is approached by a man looking for a lift into the city.
As they are driving to his downtown office, the stranger makes another request: he needs her help in retrieving a sensitive file from his office. Caroline agrees and easily collects the file, filling the rest of her day with bathing suit shopping, fending off attempted purse snatchings and giving a philandering boyfriend the boot.
It is only after this very long, very strange day that Caroline finally opens the mysterious file. Its contents will not only spring unlucky-in-love Caroline into the romance of a lifetime, it will plunge her headlong into an international adventure with the fate of the entire international banking system at stake!
