At a top secret military lab, a group of brilliant young scientists have just unlocked the secret of invisibility. The team's arrogant leader, Sebastian Caine (Kevin Bacon), ignores the risks and decides to test the dangerous procedure on himself-only to discover his fellow scientists (Elisabeth Shue and Josh Brolin) are unable to reverse the effect. Working around the clock, Caine's colleagues struggle to devise an antidote. But Sebastian's intoxication with his new-found power is growing, and he's come to believe his colleagues may be a threat to his very existence.
