Superstars Arnold Schwarzenegger and Danny DeVito team up with Emma Thompson in Junior, in their follow-up to Twins from director Ivan Reitman! Dr. Alex Hesse (Schwarzenegger) and his associate, Dr. Larry Arbogast (DeVito), develop a wondrous new drug to ensure healthy pregnancies. When the government forbids further testing of their creation, Alex and Larry secretly move forward with a daring plan...to impregnate Alex! Along the way, they must cope with a snooping, villainous research administrator (Frank Langella) and the brilliant, beautiful-but-clumsy scientist, Dr. Diana Reddin (Thompson). The seeds are sown for a hysterical, high-spirited whirlwind of humor, romance and tender insights into the magnificent power of maternal love.
