Lee Hyukjae, a top student from South Korea, is given the chance to experience the culture of the United States through a foreign exchange program. He has a bright future ahead of him being a straight 'A' student and all. However, he never has time for fun. Lee Donghae, on the other hand, has lost all motivation to pursue a future which is such a shame because he would be top of the class... well, if he actually went to class. Instead of attending class, he goes off to crazy parties where he hangs out with high school drop outs who have also lost their dreams and ambitions. What happens when Hyukjae's host family during his year stay at the United States happens to be Lee Donghae's family? Will Donghae be able to teach Hyukjae to unwind and will Hyukjae be able to get Donghae's future back on track?
