Host Howie Mandel, inspired by the Internet sensation of flash mobs, partners up with groups of strangers across the United States to help individuals deliver important announcements to their loved ones. As each person prepares for his or her event and refines the announcement, Howie is there to lend guidance. On the big day, the performances start off with only a few dancers before quickly escalating to grand-scale song-and-dance spectacles designed to make the message that follows all the more special.
