Word comes in that a scientist in Hawaii is concocting a serum that could help Blanka revert into his human form. Vega, however, also hears of this serum and wants to use it to make himself eternally young. Vega captures the scientist and holds him for ransom. Blanka is forced to give Vega the cure, in exchange for the Doctor's life. Also, Blanka makes out with the scientist's assistant while falling from a plane. Vega drops the vial of serum too, losing his chance for immortality.
