TVXQ's U-Know Younho, Lee Da Hae, Kim Bum, Park Si Hoo, Han Chae Young, and all Big Bang members in one movie? No, this is not a fanmade, this is an actual movie from 2010.
This movie is made to promote Korea's tourism: nature, beautiful scenery, delicious food, handsome stranger on a train (?), idols on ATVs (?). Well, well, I can't say this movie has great story, I don't even know what Big Bang members' role in this, and in addition to that, Han Chae Young & Park Si Hoo's story is basically a horrible version of Mr. & Mrs. Smith, but this movie will be a 30 minutes vacation for your eyes.
