One outdated bedroom. A group of excited teens. One wild weekend. Knock First is a lightning fast, half-hour, do-it-yourself show, where teenagers transform their outdated cribs into kickin' pads. The magic happens during a two-day, all night frenzy with their best friends, a hip young designer and two totally handy carpenters. The show incorporates the latest new trends, plenty of music and totally hot redecorating concepts into a show that's motivating, entertaining and okay, we'll say it, empowering. Knock First puts the exclamation point on a watershed moment that is one of the first steps to carving out an independent, adult, personal identity.
