In a secretive government laboratory, a group of scientists led by Sebastian Caine is experimenting with a serum designed to render living beings invisible. Successfully testing the formula first on animals, Sebastian recklessly decides to use himself as the human subject for the next phase of the experiment. His team, including his former girlfriend Linda McKay and colleague Matt Kensington, manage to turn Sebastian invisible. Initially, the team is elated by their breakthrough, planning to report their success to the military sponsors of their project. However, their celebration is short-lived as they soon discover that they cannot reverse the invisibility.

The inability to restore Sebastian's visibility triggers a series of events that reveal the darker sides of human nature. As Sebastian becomes increasingly isolated and disconnected from the world he once knew, his mental state begins to deteriorate. The power of invisibility, unchecked by moral or physical boundaries, leads him down a dangerous path. The scientists face a moral and ethical dilemma, struggling with the consequences of their actions while trying to find a solution. Their efforts to contain the situation and bring Sebastian back become a desperate fight for survival, testing the limits of their loyalty, trust, and scientific integrity.
