OK, here we go. This isn't the one Pioneer has out in the US now. It's a fansub. Villain likes Earth. Villain does not like people.
Villain tries to kill people.
Sailor Soldiers intervene. I won't ruin the ending, but it goes something along the lines of Sailor Soldiers beat villain. No big surprise. Aside from the plot twists and stuff, this is a normal action-movie Script. 7.9 out of 10.
