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.
