Sergei Kravinoff (played by Aaron Taylor-Johnson) and his father go hunting in Africa. Sergei Kravinoff's father was an expert hunter. When Sergei was attacked by a lion, his father thought he was just weak. Although he was bitten by a lion and abandoned by his father, Sergei did not die, but instead, the bite gave Sergei extraordinary strength. From here, immigrant Sergei Kravinoff is on a mission to prove that he is the world's greatest hunter.
