Austrian Research geneticist Dr. Alex Hesse Arnold Schwarzenegger has a nightmare about infants urinating in a library. In the real world, he and his colleague Dr. Larry Arbogast Danny DeVito, an obstetrician and gynecologist, have invented a fertility drug, Expectane, that is supposed to reduce the chances of a womans body rejecting an embryo and thus prevent a miscarriage. Unfortunately, they are not allowed to test it on women since the Food and Drug Administration has not yet approved the drug so Hesse and Arbogast move forward in their research.In response, Hesse breaks into the laboratory and locks himself in. The head of the review board, Noah Banes Frank Langella, informs Arbogast that while the FDA has denied their team the right of human experimentation, the team has managed to receive a donation from fellow geneticist Dr. Diana Reddin Emma Thompson from the ovum cryogenics department. When Hesse questions the chances of a woman taking an unapproved drug during pregnancy, Arbogast reveals that there is no need to identify the gender of the experiment and convinces Hesse to impregnate himself, using an ovum codenamed Junior. ........
