All I can remember is there were 3 kids running from bad people or someone. I think they were running in a desert at some point and stopped to rest under a tree. They heard a helicopter coming so they took their clothes off and laid them out by the tree to make it look like they were laying down by the tree. The helicopter came and started shooting at the clothes. While they watched they realized the guy shooting was their uncle? I think? and I think they called him Uncle Cricket or something.
