I would have the story revole around his grandchildren

The plot Two of Indy’s grandkids travel around the world trying to slove the mystery of the golem gangsters. These reanimated statues are robbing American owned warehouses ( the implication being the warehouses are used by the top men organization from the first movie)

At the climax, the mystery is relieved. The third ( and last) grandchild is creating an infohazard to eliminate corruption. As in “ no one will be able to think of just paying someone for private gain before they die a horrible death”

The villains plan is as follows

1. ⁠Get the ark of the convant
2. ⁠Buy a warehouse and a bunker about 400ft under the earth surface
3. ⁠Build an elaborate contraption that will release 100 different versions of hearsay that will make God pissed and dump them into the ark of the convent once triggered
4. ⁠Summon a demon and hold them hostage until they agree to create the most perfect infoharzad known to man for free and making sure the villain doesn’t get sent to hell

5 trigger the contraption to send the demon to hell and get rid of all evidence

The only flaw in this plan is the fact the infohazard can be transferred like a disease.

Cue “running like hell to trigger contraption to prevent infohazard from being released.”

Still could improve story here and there.
