Neptune 2 - Episode 2

A first attempt to enter the world-ship and make contact with the Humans
inside has failed after the exploration team was contaminated with deadly
nanorobots. Only Marie, with her Mantris-improved body, was able to fight them
off, and so she and Kim, who is also immune, make the decision to give it
another try … before the authorities of Earth destroy the massive vessel, the
robotic menace within … and its mysterious Human passengers.
