Gabriel Schist is spending his remaining years at Bright New Day, a nursing home. He once won the Nobel Prize for inventing a vaccine for AIDS. But now, he has Alzheimer's, and his mind is slowly slipping away. When one of the residents comes down with a horrific virus, Gabriel realizes that he is the only one who can find a cure. Encouraged by Victor, an odd stranger, he convinces the administrator to allow him to study the virus. Soon, reality begins to shift, and Gabriel's hallucinations interfere with his work. As the death count mounts, Gabriel is in a race against the clock and his own mind. Can he find a cure before his brain deteriorates past the point of no return?
