Host Howie Mandel puts a hidden-camera spin on the “flash mob” concept. Mandel and hundreds of strangers will help special guests plan extraordinary surprises for friends, family members, loved ones or co-workers. These unknowing participants will be shocked and stunned by surprise performances that lead up to fantastic reveals that include a husband learning that his wife is pregnant, an applicant finding out that she got the job and a marriage proposal, among others.

“It’s so exciting to be a part of this huge musical spectacle never before attempted on this scale,” said Mandel.

Throughout the hour, the guests will be shown prepping for the event – rehearsing their routines and refining their speeches – all while receiving guidance from host Mandel. Then, on the day of the big event – with the hidden cameras rolling – the detailed plan comes to fruition and suddenly explodes into a song-and-dance spectacle they are sure never to forget. What begins as a few dancers evolves into a grand-scale performance that wraps up with a life-changing announcement for the participants like nothing ever seen on TV.
