The team expects bloody murder after Nate's escape, but in stead two 'corpses' seem resurrected, in Max Ferris's case even during 'autopsy'. The crucial factor is a natural toxins combination, not unlike voodoo-zombie-powder. This and the subjects' identity all lead to retired professor Dr. Aden, who used it in secret 1970s near-death research for the Pentagon. Written by KGF Vissers

Zombies Walk in Vegas
28 January 2012 | by (Canada) – See all my reviews

When two supposedly dead bodies come back to life, the team discovers a 30 year old science program at a university that dealt in bizarre aspects of science. Guest star former WKRP DJ Howard Hessemen plays a retired discredited professor that led the project. But some modern day students have discovered his work in an old lab and are trying to make one of his experiments a reality. Meanwhile, the fallout of Nate Haskell's escape haunts Langston.

Reviewer's Comment: My only issue with this episode is that it feels like a ripoff of 'Fringe'. The old slightly weird scientist, the lab that has been locked up for a long time, the bizarre experiments, the unforeseen results, all feel like a Fringe episode. They even have a metal, water filled sensory deprivation tank in the lab. Just a bit too much for any fan of Fringe.
