Thirteen-year-old Quest (Q, for short) is getting a new family. His rock star mother just married another musician whose daughter, Angela, is fifteen. When they all leave on a concert tour in their luxury bus, things begin to get a little strange. Angela, whose late mother was a government agent, discovers that she is being followed. Q and Angela find themselves thrust into the middle of an investigation by an off-shoot of the Secret Service and the Israeli Mossad, who are all trying to find out whether Angela's mother was really killed in a terrorist bombing four years earlier. As the teens try to figure out who are the bad guys and who are the good guys, they have to use all of their skills to stay one step ahead and find out the truth.
