Agatha and Dolly, two privates stationed in a military bunker, give in to their sexual desires and make love to one another. That is until General Leal catches the two soldiers in the act, promising them that severe consequences await their return back home. The situation takes a toll on Agatha’s mental state. She takes a shower, worrying about the punishment awaiting her, too distracted by her own thoughts to notice the strange creature slithering towards her. A parasite leaps into Agatha’s vagina, invading her body and corrupting Agatha into a vile and lustful state of her former self. Dolly enters the shower room to console Agatha, unaware of what she has became. Agatha attacks Dolly in a violent manner, wanting to escalate their sexual experience here and now. Dolly tries to resist, prompting Agatha to regurgitate a parasite from her body, infecting Dolly with the very same corruption that consumed Agatha herself.
