The film begins with Johnny, Pippin, and Sarah playing Monopoly. Just as Pippin is starting her turn, Johnny hears the phone ring and answers it. Dr. Kilroy tells them to come to Egypt at once, and the adventurers head out to the airport. Once there, they meet Harry Cane, whom flies them off to Egypt. However, behind them on Tomb Robber Airlines, Lord Sam Sinister and Slyboots are closely following them.
Once in Egypt, the adventurers stop at a McDonald's to eat lunch while the villains peer in through a window. As they lament over the prospect of getting better food than their expired lunch meat, Crazy Ali walks up and immediately volunteers to join their gang. Lord Sinister insults Crazy Ali, but Slyboots welcomes him in with open arms.
After lunch, the adventurers get a ride in a taxi driven by a wild taxi driver who smashes fruit carts to get food and water towers to get a drink. Once he gets to the Cairo Hotel, he swerves into the hotel lobby, drops off the adventurers, and drives out the front door. They check in and head up to their room, only to discover that the walls are plastered with chewing gum. They head back out to head to the museum.
Once they get to the museum, Dr. Kilroy welcomes his friends and immediately begins to tell them the myth of Pharaoh Hotep, who is said to have turned greedy. Then he mentions that a curse was put on the gem Re-Gou that whoever touches it will die. They head to the Nile River to get the boat Dr. Kilroy rented, only find a paper boat held afloat by Mountain Dew bottles. Crocodiles eat the boat and its owner, and Dr. Kilroy directs them to the real boat.
In their boat, named The Navigator, the adventurers and their boat driver travel down to the Temple of Horus, with Lord Sinister and his men following. At the temple, the boat driver guards The Navigator while the adventurers enter the temple. They solve the puzzles and retrieve the Eye of Horus. They head down to the boat and sail off to the Sphinx.
On the way to the Sphinx, Lord Sinister and his men catch up to the adventurers. Crazy Ali shoots the boat driver dead, sending the boat crashing into the sand. Thinking no one survived the crash, the villains speed off. The adventurers inspect the Sphinx, then Johnny uses the Eye of Horus to retrieve the Skull of Anubis. From there, they hike out to Hotep's tomb.
Out in the desert, the adventurers get stopped by bandits who turn out to be just a mirage. Soon after, they reach the tomb. They all race in, only to be captured by the villains. Sarah bargains for her father's life, and Johnny finds a secret lever. He uses the Skull of Anubis to trigger the lever, and Re-gou appears. Crazy Ali grabs Re-gou, awakening Hotep's mummy. Hotep melts Crazy Ali and Slyboots, then faces Sarah. With instruction from Dr. Kilroy, Sarah destroys Hotep, which then triggers an earthquake. Everyone gets out of the tomb in time.
Back in Cairo, Harry is about to call for a taxi when Sarah shushes him. They walk to the airport.
Little is known about the production history of this film. What is known is that the story is based on two stories called The Mummy's Tomb and Mummy's Curse, written by Daniel and Andrew Bermudez respectively, that prominently featured the LEGO Adventurers characters. The script was most likely written in 2004, with a planned release in either 2005 or 2006. However, due to other commitments at the time, including the Cornerstone Thespian Society and a company name change, this film was shelved and ultimately forgotten. The current copy of the script was re-printed from the original file and is believed to be the oldest surviving Mustache Maniacs Film Co. script.

Johnny Thunder and the Curse of the Mummy contains examples of the following tropes.
- Ace Pilot: The character of Harry Cane.
- Adaptation Expansion: This film is based on a pair of short stories titled The Mummy's Tomb and Mummy's Curse, which are based on the 1998 LEGO Adventurers sets. This story is basically the two stories mashed together, but other details, like the ruins, were not in either short story.
- Adventurer Archaeologist: All of the adventurers are this, naturally.
- Adventurer Outfit: A good number of the heroes and villains wear a varying degree of explorers' attire.
- Curse of the Pharaoh: When Re-Gou is disturbed, Hotep rises and kills both Slyboots and Crazy Ali.
- Denser and Wackier: Since LEGO produces children's toys, and therefore tailors its stories for young kids, the original story was fairly family-friendly. But this film takes that several steps further. The villains eat expired lunch meat, the taxi driver that lives in his car destroys fruit stands to eat and water towers to drink, the hotel room is plastered with chewing gum, a boat for hire turns out to be a paper boat held afloat by Mountain Dew bottles, and so forth.
- Drives Like Crazy: The taxi driver drives his taxi this way.
- Eye of Horus Means Egypt: One of the clues needed to find the treasure is literally the Eye of Horus.
- Fruit Cart: The taxi driver smashes into one because he lives in his car, and this is how he eats.
- Hollywood Mirage: Near the end of the film, the Adventurers think that they see a pair of bandits race up on horseback, only for them to disappear.
- Mineral MacGuffin: Re-Gou is this.
- Mr. Exposition: Dr. Kilroy's primary role here is to simply tell everyone else about the legend and curse of Hotep.
- Mummy: At the end of the story, Pharaoh Hotep rises from the dead and kills both Slyboots and Crazy Ali.
- Plot Coupon: Both the Eye of Horus and the Skull of Anubis serve this purpose, as they are needed to find Re-Gou.
- Random Events Plot: While subverted in that there is a coherent story here, the gags and jokes fall under this trope, such as the hotel room plastered with chewing gum, which do nothing to advance the plot forward.
- The Taxi: The Adventurers take one to the hotel, with humorous results.
- Temple of Doom: The ruins throughout the story are lined with booby traps.
- Too Dumb to Live: The boat owner that Dr. Kilroy hired turns out to own a paper boat held afloat by Mountain Dew bottles. The boat immediately sinks and crocodiles eat the boat owner, leading Dr. Kilroy to find another boat.
- This is the first Mustache Maniacs Film Co. film to feature a script (all of our films before then were made "on the fly").
- This is believed to be the oldest surviving Mustache Maniacs Film Co. script.
- The character of Sarah Thunder, who plays a large role in Johnny Thunder and the Gift of the Nile, first appeared in this script.
- Because this film was based on the short stories The Mummy's Tomb and The Mummy's Curse, Crazy Ali was originally going to be called the City Slicker, the name he had in the latter story.
- Neither the boat owners nor the taxi driver have any given names.
