Lap starts out as a regular reporter but when his relative Jang comes, he finds himself trapped in another world. Jang has a special chemical that makes you disappear (become invisible). Lap tries it and of course, he
disappears. But most of the time, you can see him. With a hard-working policewoman, Nam, they solve cases together, including ones with disappearing people. Nam finds herself in love with Lap, but he only loves reporter Wing.
