The Posse is the story of what happens after the big finale of a reality TV competition and of a small town girl's ride through Hollywood. When seventeen-year old Jacey Chandliss enters and wins Generation Next: America’s Top Young Actress, an American Idol-type contest that offers the winner a star-making role in a major Hollywood motion picture, she’s thrust into the bright Hollywood spotlight. She’s got a bonafide Hollywood power-agent and she’s living in L.A. for the summer. It’s all a lot to handle, and Jacey would probably buckle under the pressure if she didn’t have her friends along for the ride. Her best friends Dash and Desi and her cousin Ivy are part of Jacey’s Posse. They’re going to Hollywood with Jacey to keep Jacey from going Hollywood.

Jacey is trying to prove to herself, and to Hollywood, that she really does have what it takes to succeed in the business. But thanks to intrusive paparazzi, life gets even more complicated for Jacey. Everything’s more intense—and more public—in the Hollywood spotlight.

Now that Jacey Chandliss is a bona fide Hollywood actress with two movies under her belt, it’s time for her to return full circle to the very show that launched her career—Generation Next. This time around she’s a judge, not a contestant—and she’s about to find out that being in the judge’s hot seat can be even more nerve-racking than being in the spotlight. Contestant Toby Adams manages to win the hearts of millions of viewers, but has he also managed to win his way into Jacey’s heart? What does that mean for her budding relationship with Hollywood bad boy Matt Canseco? The tabloids are already starting to raise questions—that is, when they’re not having a field day with the huge failure of Galaxy, Jacey’s first big studio flick. When everything starts to spin out of control for Hollywood’s newest It Girl, she'll need her hometown friends—Dash, Desi, and Ivy—more than ever.
