Crazy, colorful Buster and Martha Smith, an elderly couple, are awaiting the arrival of their children and grandchildren for a traditional Christmas homecoming. They reminisce, in flashback, about the Christmas of 1955 when their youngest son, Ernest, hid "Santa," a man who had just robbed the bank, in their attic. While the robber tells Ernest fantastic stories to keep him believing, Buster tries to find the stolen money to earn the $1,000 reward to provide a good Christmas for his family. Martha must remind him of the real meaning of the holiday. Later the robber gives up and tells Buster about the reward for his capture, $10,000. Hilarious and heartwarming.
