Dave Pulaski's wife is dead, and he knows who's to blame. Walt Freeman-the man who unleashed a medical experiment that turned Dave's quiet town into a bioscience nightmare. He goes to Los Angeles to get revenge. But his mission is sidetracked when he helps Sasha, a Russian girl who escapes Walt's government-funded lab. Now, an ex-military sociopath is on the hunt for both of them. Chances are, Dave will die before he can save the girl and deliver retribution. But the killer may not be the worst threat. The bioscience experiment unleashed cutters, genetically engineered mutants who flay their victims. Dave has to avoid them, outsmart the sociopath, and get revenge. And there's an even bigger problem. Sasha might be a mutant herself.
