SONG Soo-jung is a producer going on her third year at a small company. Her specialty is human interest stories. She is driven to produce these shallow stories for the sake of her ambition of one day becoming Korea’s own Oprah Winfrey. However, she is reaching the end of what’s left of her pride. One day, after months of not getting paid, she leaves her office with the company camera to produce a story on a lion apparently refusing to eat its meal. On her way, however, she comes across a robber, but she is saved somehow by Superman in a Hawaiian shirt. “Superman” claims he’s unable to tap into his supernatural powers as the bad guys have placed kryptonite inside his head. However, he doesn’t let that get in his way from helping others, from saving the world from global warming to saving a lost puppy. Soo-jung can see this will make a good story and, with a little tweaking and a little fabricating, she produces the Superman Saves the World documentary which goes on to be a ratings hit. However, the true story behind this “Superman,” including the bullet and not the kryptonite that is lodged in his brain, helps the frosty, calculating Soo-jung to awaken to what’s truly important in life.
