Naruto meets an old man, a construction worker named Gennou. However, when Gennou steals plans for some of the building in Konoha, he is pursued by the ANBU. It turns out Gennou is actually an expert Trap User ninja and was listed in the Bingo Book. After Gennou blows himself up with exploding tags strapped to his chest, the plans go missing. Fearing an invasion of Konoha from whoever hired Gennou, Tsunade asks Shikamaru to have himself and the ten Konoha Genin to keep an eye on things. When they can't find information from anybody, there is only one person who might be able to give them the information they need...Naruto.
