The major sub-plot circles around the youngest Griffin, Stewie, who has a near-death experience at a pool when a lifeguard chair falls on him, but he survives. After having a vision of being in Hell, he decides to change his ways, but this doesn’t last long. While watching television, he and Brian spot a man that looks like Stewie. Brian is convinced that he is Stewie’s real father, until Stewie learns that the man is actually himself as an adult, taking a vacation from his own time period. Baby Stewie visits thirty years later to discover that his adult self, going by the name Stu, is a single blue-collar middle-aged virgin working at a Circuit City-type store. Meanwhile, Peter and Lois are trying to teach their two older kids, Meg and Chris, to date. In the future, Chris, who hasn’t changed much, is working as a cop and is married to a foul-mouthed hustler named Vanessa. Meg is now called Ron, since she had a sex-change after college.

Billy Madison is a non-working, non-educated slacker who lives entirely off his dad. He spends his day drinking beer, reading girly magazines, and hanging out by the pool. When his father realizes that Billy is unfit to run the family business, Billy decides that he must go back to school and earn a real education. He figures it will be no problem going back to high school and learning over again, until he learns that his father bought Billy’s passing grades all the way back in elementary school. Thus, Billy must return to elementary school and pass each grade one at a time in a short time, or else he loses his place as heir to the company. In addition, Billy tries to win the hand of Veronica, a sexy school teacher who thinks her students are more mature than Billy.

Owen Baker is a 12-year-old loner who has been working as a neighborhood dog-walker so he can earn the privilege of getting a dog of his own. His hard work pays off when his parents let him adopt a scruffy mutt he names Hubble. Both boy and dog get more than they bargained for when Owen wakes up one morning to discover he can understand every word Hubble says, including the ominous phrase: “Take me to your leaders.” Owen learns that dogs came to Earth thousands of years ago to colonize and dominate the planet. Hubble (who is really named Canid 3942) has been sent by the powerful Greater Dane on a mission from the Dog Star Sirius to make sure dogs have fulfilled this destiny. Despite the best efforts of Owen’s rag-tag group of neighborhood dogs to convince him otherwise, Hubble soon discovers the awful truth about Earth dogs: “You’re all pets!” Now Owen (a boy who never had a friend) and Hubble (a dog who never needed one) must work together to prepare the neighborhood dogs for a visit from The Greater Dane—or all dogs will be removed from the planet! The fate of Earth dogs hangs in the balance, and it’s up to Owen, Hubble, and their canine companions to save man’s best friend.

It has been four years since the alien-seeking agents averted an intergalactic disaster of epic proportions. Kay has since returned to the comforts of civilian life while Jay continues to work for the Men in Black, the highly funded yet unofficial government agency that regulates all things alien on earth. While investigating a seemingly routine crime, Jay uncovers a diabolical plot masterminded by Serleena, an evil Kylothian monster who disguises herself as a sexy lingerie model. It’s a race against the clock as Jay must convince Kay—who not only has no memory of his time spent with the agency, but is also the only person alive who has the expertise to save the galaxy—to reunite with the MIB before Earth is destroyed completely.

Little Nicky is “daddy’s little girl” in Hell. He’s the son of Satan, who got the job from HIS father, Lucifer. Satan wants to retire, but none of his sons are good enough for the job. There’s Cassius, who’s big and strong, but lacks the ‘goodness’ to make the job real. There’s Adrian, who while really hot (no pun intended) and smart, has no goodness at all. Then there’s Nicky [Sandler] who, while having good, lacks any evil whatsoever. As seen in the previews, he is told to release his evil. He needs to release it to save his dad. Cassius and Adrain leave Hell, thereby freezing the wall of fire that lets the damned souls into Hell. Since no souls can come in now, Satan starts to die. It’s up to Little Nicky to go and get his brothers, putting them into a flask and bringing them back to Hell at the exact same time to save Satan from decomposition. If Nicky ‘dies’ on Earth, he will be able to get through the frozen wall and back up to Earth. The catch is that he has only a week, and that Adrian and Cassius are MUCH more powerful than he is.
