Star Trek: The Next Generation: Infiltrator

Centuries ago, followers of the tyrant Khan Noonien Singh left Earth for the
planet Hera to continue his experiment in selective breeding. Now, they are
finally ready to launch their plan of universal domination -- with the
U.S.S. EnterpriseTM as their weapon.
Captain Picard must enlist the help of Heran expatriate Astrid Kemal to defeat
her fellow superbeings. Unless the captain and crew of the Enterprise
can stop them, the Heran infiltrators could alter the genetic landscape of the
galaxy for generations to come.
