Detective Davis Tillinghast is a modern day Sherlock Holmes, using his keen intellect and powers of deduction to solve the cases no one else can ... until now. A series of bizarre and seemingly impossible mutilations have him stumped, the only tenuous clue leading back to the laboratory of his estanged brother Crawford, a crazed genius obsessed with inter-dimensional physics. Crawford has invented an instrument that hyper-stimulates the pineal gland of the brain, making visible the many thousands of parallel universes that occupy our space/time continuum. But unbeknownst to him this machine is also empowering creatures from other realities, giving them the ability to "drift" - travel between dimensions. Davis discovers that a "drifter" has been causing the random mutilations and sets out to destroy his brother's machine. In the process, Davis is exposed to a vast amount of the machine's energy, turning him too into a drifter.
