The gateway to idol stardom might have opened for the newly formed singing group Wake Up, Girls, but the path to fame is full of perils and pitfalls. For Mayu, Airi, Minami, Yoshino, Nanami, Kaya, and Miyu, it is going to be especially difficult to know who to trust, as their manager Matsuda's lack of experience could give other, less scrupulous individuals a chance to take advantage. That situation quickly comes to a head when Green Leaves' president suddenly disappears with most of the money, and things only get worse when the replacement producer seems more interested in getting the girls into revealing swimsuits than promoting their music. As malicious gossip begins to surface regarding Mayu's past membership in a rival group, and internal tensions begin to tear the team apart, they will need more than just ambition to survive. Singing may be a business, but friendship and a love of music is what will keep everything together.
