Sebastian (Kevin Bacon) becomes the first human subject to be turned invisible for a top-secret Pentagon project. When ex-girlfriend Linda (Elizabeth Shue) and other team members try to return him to normal, the experiment fails. While invisible he makes mischief, including raping the hot chick next door. He also finds out that Linda is sleeping with a co-worker (Josh Brolin) and goes on a murderous rampage (they also want to shut the program down). He kills the rest of his team, blows the building up, and tries to kill Linda and Matt, but they kill him instead and escape just in the nick of time to a waiting ambulance.
