The scene right after where Willie says "Now let's get out of here" and Indy says "Right, all of us".
When it cuts to the mines, and the kid falls, and the guard picks him up and Indy is standing there in silhouette, John William's music blaring. Then showing the kids and hearing the punches, and the guard slides across the ground unconcious. Then the kids looking back at Indy, smiling with renewed hope they are getting out of it all alive. I still get goose bumps. That's actually one of my favorite scenes out of all 4 movies. Classic Saturday afternoon serial stuff, and classic Indy.
