Three kids, Mario Yedidia, Adam Wylie, and Clara Bryant all of them into those monster/horror classics are spying on an eccentric neighbor played by Ed Lauter. They've heard all kinds of neighborhood rumors about how this guy just might not be quite human. But he's human enough to scare them off his place.
But not before they discover an ancient Egyptian sarcophagus in his basement and the kids accidentally reanimate the mummy inside. After that the silliness kicks into high gear.
And basically that sums it up for Under Wraps. This is obviously for a kid's G rated audience, but I'm not sure about what age people will think this funny instead of silly. The kids have an alleged adult as an accomplice in their adventure, Ken Hudson Campbell who runs one of those science fiction/horror type specialty stores. But he just looks foolish running around with the juveniles.
Bill Faggerbakke plays the mummy and he's got a girlfriend mummy who was his sweetheart those thousands of years ago in ancient Egypt. He'd like to be reunited with her. Of course you'll remember this in a more serious vein as the plot of the original The Mummy film classic with Boris Karloff.
This one doesn't come anywhere near, but it should give you an idea of what to expect.
