Will I just get old, and die?” These thoughts scare Suzume… The ordinariness of her life is interrupted one day when she spots a flier in the stairwell advertising for spies! Intrigued, Suzume phones the number. Three days later, Suzume is instructed to go to a run down apartment. She is greeted by a man and a woman – he is unemployed; she is a shopping mall announcer. They claim to be spies working for a foreign state. Just like Suzume, they are ordinary people with ordinary lives. The couple persuades Suzume to become a spy too. They virtually force the 5 million yen first mission fee on to Suzume, and so begins her life as a spy!
