An invading alien Slime attaches itself to the hull of the ship, while a rogue sex robot enters from the opposite hallway. The space marine caught in the middle fears for his life... at first that is. Rather than fighting each other, the slime girl and robot girl realize that they have a mutual goal which could be much easier to obtain by working together: to extract some male sperm for their own respective purposes. For the slime girl, it is her nutrition, for the robot girl, she wants to bring it back to her own tribe for some unknown purpose - possibly some type of research. As for our space marine, he is far more than willing to oblige.
