Goro, a criminal mastermind, plot to steal a massive cache of gold from the Rossini family. Unbeknownst to Goro and his soldiers of fortune, one of Rossini's guest is a highly trained foreign operative who fights to not only save the hostages and the gold, but his imperiled family.
Living among boys is easy, each of them with their own mess, unregimented lifestyle, and unique "method of study." The male universe in which they live, however, is about to be invaded by women. Giorgia is independent and receives little attention from her parents; Francesca is in a doomed relationship with an older professor, while Emma wants to be a famous performer. In this new mixed arrangement house, each character finds their place as they establish a confusing, but fun and tumultuous extended family - a family which none of them has ever truly had.
