This time, the adults have shrunk themselves, and the kids need to fix it.
Wayne Szalinzki, a wacky, absent-minded inventor, is back again but only this time he decides to use his infamous shrinking machine just one more time. His wife, Diane, asks him to get rid of the Tiki Man, a large tiki sculpture. He refuses to get rid of it so he decides to restart the machine and reduces it to pocket-size. However, the machine is accidentally activated and Wayne ends up shrinking himself and his brother, Gordon. Meanwhile, when Gordon's wife, Patti, and Diane were going on a vacation they come back when Patti suddenly realizes she forgot Mitch's medicine for his potassium deficiency. When they're about to leave, they decide to sneak into the attic and surprise their husbands, but the machine is activated once again, and they're shrunk as well. So the adults must be very brave of disgusting household insects the size of dinosaurs and more in their biggest adventure to get their children's attention.—Anthony Pereyra <[email protected]>
As if shrinking his and the neighbors' children in Honey, I Shrunk the Kids (1989), and zapping his son, Adam, in Honey, I Blew Up the Kid (1992) weren't enough, the well-meaning inventor, Wayne Szalinski, gets neck-deep into trouble, when his shrinking machine gets into action. This time, it shrinks not only Wayne and his brother, Gordon, but his wife, Diane, and sister-in-law, Patti, too. Meanwhile, the kids think they have the house to themselves, however, their minuscule parents hear and see everything, even though they have a hard time navigating in the vast and perilous household environment while doing battle with gargantuan insects. Will Wayne never learn?—Nick Riganas
After eight years have passed since the previous events, ten-year-old Adam now wishes to attend baseball camp, a notion foreign to his father, Wayne, but more comprehensible to his mother, Diane. With their older children, Amy and Nick, away at college, Wayne and his brother Gordon have launched Szalinski Labs. When they receive tickets for a shuttle landing, Diane reminds Wayne over the phone that he needs to look after Adam and his cousins, Jenny and Mitch, while she and Patti, Gordon's wife, are on vacation. She also insists Wayne get rid of a Tiki Man sculpture she dislikes, though Wayne sees it as a good luck charm.
With Diane and Patti on their trip, Wayne and Gordon's plans bore the kids. To secretly shrink the Tiki Man without Diane knowing, Wayne sends the kids to the store. However, they end up accidentally shrinking themselves when a billiard ball activates the machine. Meanwhile, Patti remembers Mitch's potassium medication and heads back home, only to be shrunk alongside Diane by the same mishap.
Back home, the kids, unaware of the adults' predicament, assume they are alone and Jenny invites her friends over. The shrunken adults use a Hot Wheels track to navigate but end up in the laundry, eventually tumbling out in front of Adam and Mitch, who Wayne realizes has a strong interest in sports, not science.
Realizing Mitch's need for his medication, the adults journey through the house, encountering and defeating a cockroach, using a bubble machine, and narrowly escaping a bowl of onion dip. In the kitchen, Patti and Diane help a daddy long-legs, symbolizing Diane's realization about the challenges of being small.
Wayne and Gordon rewire the stereo to amplify their voices, while Mitch's fainting from lack of medication is remedied by Adam's quick thinking with bananas. Jenny confronts her crush Ricky, earning her mother's respect, and the adults' voices through the stereo scare away the unruly boys.
The kids decide to unshrink their parents, who re-evaluate their parenting methods. Wayne supports Adam's baseball interest, Diane compromises on the Tiki Man, and Wayne chooses to return to inventing.
Life returns to normal: Adam excels at baseball camp, Wayne gains a new appreciation for the sport, and the Tiki Man, now in the backyard, stands twice the height of the house.
