Chronically underemployed Rei Shimura takes a freelance gig with a Washington, D. C. , alphabet agency that just might have ties to the CIA. Her mission, should she choose to accept it, is to go undercover as a clerk in a big Tokyo department store. It's a tricky and risky assignment, but it also gives Rei the opportunity to check out all the latest fashions and use her store discount to indulge her shopping impulses. Meanwhile, hile, she's listening in on conversations not meant for her and crashing a conference she's not invited to. She winds up fending off the advances of a couple of the store's executives who seem to be fascinated by her navel ring. When her cover is blown, Rei is in big trouble, and it will take all her resourcefulness and unorthodox methods to unmask a killer.
