Hours after the events of the Species II, the medical van transporting the lifeless Eve has lost its way, but when the co-driver tries to radio their superiors, the driver stops and holds him at gunpoint. They are ambushed by the "half-breed" alien child hiding in the van, who kills the co-driver with his tongue. The driver discovers both the half-breed and a reviving Eve in the back of the van; the half-breed strangles Eve to death while she gives birth to a newborn alien, which the driver flees with. Government agent Wasach orders an autopsy, discovering Eve's pregnancy, then has her body burned.
