The gang's back for a very special summer at the Hills--Camp's 50th Anniversary! Wiener is pumped to show his little brother, Max, that he's a Legend. But when his friends treat him like they always do (which is the butt of the cabin's jokes), Wiener fears he's losing serious big-brother cred. So when a slick exchange student from Barcelona joins their cabin, Wiener sees an opportunity to prove himself to Max once more, even if it means jeopardizing his budding romance, his friends, and at times, his life. Meanwhile, inspired by a big change at home, Missi is determined this summer to be one hundred percent true to herself--no more pretending to like celebrity teens just to fit in! But when the Barcelona native pays her special attention, she struggles to choose between being the true farm girl she is and being the pretender. After a big, law-breaking secret about the new kid gets unleashed, Missi and Wiener are sent spinning. To set things right, it will all boil down to . . . a hoedown showdown.
