Plot Synopsis

Hosted by Ryan Seacrest in a Los Angeles-based studio, this one-hour reality series follows KNOCK KNOCK LIVE's team -- co-hosts Adrienne Bailon, Jordan 'Shorty' Johnson, Chuey Martinez, Ross Mathews, Kellie Pickler & Tyler Posey -- traveling across the country, to any city at any time, surprising unsuspecting people at their front doors with a chance to win big cash prizes, meet their favorite celebrities and turn their wildest dreams into reality. The lucky people might have the chance to play a game of H-O-R-S-E with a pro basketball player for the chance to win courtside seats, host a concert on their own front lawn for one of the biggest pop stars in the world, or any other event that takes an ordinary day and makes it unforgettable. David Beckham, Justin Bieber, Ariana Grande, Florida Georgia Line, Common, Rob Gronkowski, Robin Thicke, Meghan Trainor, Rita Ora, Martha Stewart, Luke Bryan, Lea Michele, Mike Holmes and Bubba Watson are all scheduled to make special appearances.
