Howie Mandel and thousands of strangers will help a woman plan an extraordinary surprise in order to present her longtime boyfriend with an ultimatum of either getting married or breaking up. 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, with an official appearing at the end to deliver vows to the couple - either her boyfriend says "I do" or she says goodbye.
