He takes a break from his work to go on a trip with three friends. He admits to his friend Sophia (Nicole Vicius) that he loves her – but shortly after this she falls into a nearby lake and drowns.Using the methods from his research project he is able to revive her, but the process requires that he extract the hormone Oxytocin from a recently-dead corpse. He murders two women, and attempts to murder a third, in the process of keeping Sophia alive. His actions arouse the suspicion of his friends and the campus police.
