So, this guy has some money, loves Portugal, and buys a small farm. On the farm is a large concrete-block storage barn. The doors are welded shut. He bought the place without knowing what was inside.
Could have been hay; Could have been old farm equipment. Maybe, just maybe, it might have been a nice collection of aging port wine, in which case he might make a buck or ten off the deal.
So, he grinds the welds off the steel doors, opens the place up and guess what he finds. (No, it wasn't a weed farm!)
