Herbert West is an ambitious ,driven doctor in his mid 20s , he would rather qualify himself as a researcher about the key for life and immortality , an obsessive mad scientist with grandiose ideals, who doesn't believe in rigid fatalist way to view death ,rather challenges traditional thinking to push the boundaries of knowledge ,he created a serum that he calls the Re-agent ,it's a re-animation formula that brings dead back to life with an uncontrollable agressive impusles and thirst for human flesh , he knows no limits of ethics or morality or any of those shackles to the potentiality of science .
