Dr Kim works at the Korean equivalent of NASA. He has talent, brains and is unparalleled with his programming skills. One day, he hacks into the Mars Rover and catches the glimpse of an alien. Unfortunately, the device wasn't recording at the time and so he has no proof and clearly no one believes him. And as fate may have it, that alien has come to Earth believing she had been caught on video and wanting nothing more than delete that proof before her boss finds out. Misunderstandings ensures as the two characters meet and are forced to work together as a new group of aliens start stirring trouble on Earth.

This is a story about aliens. Yes, aliens. Choi Sera houses displaced aliens in her home, where they all pretend to be UFO fanatics in order to explain their eccentricities. Sera’s job is to teach these aliens how to live in human society—not that difficult on the surface, as they ostensibly look like humans (except for the three fingers on each hand thing). They look normal, and they can communicate with earthlings via a translator that looks like a hearing aid, but can they act normal? The answer to that is a resounding no. Watch as Sera tries to school the emotionless twins, Seunghyun and Seungmin (really clones) on dating (with disasterous results), tries to keep Hyunwoo out of trouble, and keep them all from being taken away by the UN alien hunter who’s on to them. And what happens when a translator breaks?!
