In the age of space exploration, [Vectors] are assassins who
make a living transporting resources and unknown objects.
Rookie Vector Grace (Liza) sets out on the job with her best friend and partner, Effie (Veronica),
and the youngest and most experienced Vector Al (Tomoe).
But one day, Al's behavior changes.
Attacked by a released tentacle creature, Grace remembers
another side to herself that she has forgotten.
Grace and Al are members of a dark organization that traffics women.
And this time, their target is none other than Effie!
Her body is taken over by the tentacle creature that has parasitized her,
and she is at the mercy of its perverse desires and pleasure, but she resists, trying to protect Effie.
Will Grace be able to protect Effie from the evil clutches of the organization...?
