15살 소년 Bobby 는 어느 날 아침 잠에서 깨어 자신이 투명인간으로 변신한 것을 알게된다. Bobby의 가족들과 투명인간 친구 Alicia 는 그를 정상으로 돌이키려고 하는데... Bobby Phillips is an average fifteen-year-old-boy. Until the morning he wakes up and can't see himself in the mirror. Not blind, not dreaming-Bobby is just plain invisible. There doesn't seem to be any rhyme or reason to Bobby's new condition; even his dad the physicist can't figure it out. For Bobby that means no school, no friends, no life. He's a missing person. Then he meets Alicia. She's blind, and Bobby can't resist talking to her, trusting her. But people are starting to wonder where Bobby is. Bobby knows that his invisibility could have dangerous consequences for his family and that time is running out. He has to find out how to be seen again-before it's too late.
