Plot synopsis
It is Christmas Eve at Mario Brothers Plumbing, where Luigi is in the middle of polishing his boot. Telling himself that he needs to hurry up before Mario returns, Luigi points out that he is barefoot, and that his own boots are the only present that he can afford for Mario, due to the fact that business has not been good lately.

Approaching the front door, Mario announces that he has returned with Christmas dinner. Before Mario can enter, Luigi tells him not to enter yet, as he needs to finish wrapping his present, which he does with old newspaper. After placing the wrapped present underneath the brothers' puny Christmas tree, Luigi sits down at the table, and allows Mario to enter. Carrying some grocery bags, Mario comments about the cold weather, stating that if he stepped on a dime with his old boots, he could tell whether it was heads or tails, if he could even find a dime to step on.

Anticipating the feast that Mario has brought home, Luigi is disappointed to see Mario empty two measly garbanzo beans from the bag onto a plate. Mario states that even though the beans were all that he could afford, they will plump up when cooked. Luigi takes the beans, and tells Mario that he will place them in his soup to add some flavor, as he heads over to the stove. While Luigi is at the stove, Mario tells him to close his eyes, because he is about to give him his present. Mario removes his special wrench from his tool belt, places it in the empty grocery bag, and places the bag under the tree.

At that moment, the doorbell rings, and Mario offers to answer the door for Luigi. Upon opening the door, Mario sees a man in red long johns and a long, white beard standing there, asking if he can use their phone. The man comments that he is very tired and that somebody stole his transportation. After the man falls into Mario's arms from exhaustion, Mario tells Luigi that they now have company.

Later on, Mario and the man, whose name is revealed to be Nick, are sitting down at the table, eating their soup. Because Nick finished his bowl, Mario kindly offers his own to Nick. Luigi, having gone outside earlier, returns and complains about the cold weather, then tells Nick that he had been all over the neighborhood, but was unable to find his things. Noticing that Luigi is in his socks, Mario asks why he is not wearing his boots, and Luigi makes up a story about how he took them to a shoemaker.

Luigi asks where his soup is, but Mario implies that he offered his bowl to Nick, to which Luigi does not mind, as he comments that he might as well get a head start on his New Years diet. Having finished his second bowl of soup, Nick thanks Mario and Luigi for their hospitality. The CooKoo Bird comes out of the wall, alerting Mario, Luigi and Nick that it is now midnight, therefore Christmas Day, and wishes them a Merry Christmas.

Mario and Luigi excitedly head over to the tree and pick up their presents, to which Nick comments that it must be wonderful to receive presents on Christmas, implying that he has never received a Christmas present in a long time. Feeling sorry for Nick, Luigi tells him that he and Mario have already opened theirs, and offer their presents to Nick. Nick opens the presents, and is thrilled to receive the boots and the wrench.

After waking up the next morning, Luigi, in his pajamas, heads over to the tree and is surprised to see that Nick had returned their presents to them. Mario finds a note in the tree and reads that it was from Nick, who wrote that the cops found his transportation, and that there was a surprise under the seat for them. Mario then reads that the note is signed S. C. As Luigi comments that he thought the man's name was Nick, he and Mario look out the window to see reindeer pulling Santa Claus' sleigh.

Luigi asks Mario if Nick really could have been Santa Claus, to which they respond with "Nah!” Mario and Luigi wish each a Merry Christmas, then give each other a big hug, and a kiss.
