I look for movie I watched in the end of 90’s. I don’t remember the beginning or the end. Man and woman were digging some bag of money at night , somewhere in the desert. They were using external light box put on the bonnet of their pick-up. They digged deep hole and start losing hope , but finally they found big bag full of money. On the next day they washed the money. Literally. They put them in a laundry machine and then hook them with peg on cord to dry.
