The following day, Paul visits the lab at Natalie's invitation. He gets into a fight with Yuri, who attacks him with the werewolf skull. Paul is scratched by the skull, and now it is his turn to start showing symptoms of lycanthropy. He starts attacking people at night, but remembers little of it. Finally, Natalie and Yuri spy him changing. Yuri plots to capture Paul and take him to the lab, and convinces Natalie to help him. In a murky chase sequence, Paul, in werewolf form, kills Yuri. He and Natalie (now a werewolf, herself, with no explanation as to how she became one, although the trailer of the film hints at a sex scene not shown in the film) reunite at the end of the movie.
