Once again, those randy monsters try to break into an underground lab of dubious intent and the only man whose ever fought them does nothing to help anyone but himself to some horny waste-lander. But this time, he fathers his own monster baby. Daddy's home, sucka!
Continuing the story of David, one of two survivors from Mojave Lab of the first film, we find him on his way to Rocky Mountain Lab where he plans to spend the rest of his days on a weekend booty/peyote hunt. I guess they don't have vaccines to the virus that killed all of mankind but now they have a method of creating one. The sole missing ingredient comes from cacti that he must gather for them on his way. As one could predict his journey is hampered by the monsters as well as a cult that sacrifices hot ladies to the monster's lusty ways in order to save themselves (that doesn't make sense). He meets a randy lady who comforts his grief for the world by offering up her luscious bits. She manages to get pregnant with his child only to later have the monster have his way with her creating a super mutant monster baby within her. The terror!
