Buck Shatz is an eighty-seven-year-old retired Memphis cop with a know-it-all plugged-in grandson for a sidekick. When Buck learns that an old adversary may have escaped Germany with a fortune in stolen gold, he decides to hunt down the fugitive and claim the loot. But a lot of people want a piece of that stolen treasure, and Buck's investigation quickly attracts unfriendly attention from a very motley (and murderous) crew.
