Merry Christmas, Mr. Bean

Act 1: Christmas Shopping

Seeking to prepare for the big day, Mr. Bean ventures into town on Christmas Eve and visits Harrods to buy some Christmas decorations, continuing his trend of behaving inappropriately in such a prestigious department store. After parking directly at the front of the store, and harassing a man dressed as Father Christmas by pulling on his false beard^[6], Bean proceeds to test two different types of baubles, going with one that bounces off the ground (after the other one simply smashes on the floor). He then looks to test out some Christmas lights, and managing to get into a storeroom while an employee is busy dealing with a customer, tries it out on a socket being used for the store's exterior lights, plunging the entire exterior of the store into darkness in the process.

As the employee sorts out his purchases, Bean spots the shop's Nativity scene display and performs a creative yet inaccurate story by playing around with it and some nearby toys, first by making some of the figurines shush anything that could wake the baby Jesus, having a shepherd figurine round up some toy sheep, and then having two toy tanks and a toy Dalek battle with a toy T-rex, eventually having the little baby Jesus figurine airlifted by an angel attached to a magnet hanging down from a toy helicopter to the bedroom of a doll house alongside his parent's figurines. His fun is soon disrupted by the store manager - introducing a toy policeman into the Nativity scene to halt proceedings - who hands him his purchases and watches as Bean leaves the shop.

Following his fun, Bean heads to a local Christmas market, where he meets up with his girlfriend, Irma Gobb, and is dragged to the shop window of a jeweller's, whereupon she tries to give him the message that she wants a sparkly ring in the display by pointing to a portrait of a couple getting engaged. Bean nods to her in agreement (albeit expressing disgust when she kisses him on the cheek), and heads into the shop, much to Irma's delight. After buying something from the jeweller, Bean spots another man dressed as Father Christmas, and proceeds to tug on his beard, only to find it was indeed real, prompting him to make a quick exit while the man recovers. Bean then takes part in a "guess the weight" game, with the prize being a large turkey; he manages to cheat his way to victory by making use of scales and a calculator to determine the correct weight.

Afterwards, Bean volunteers to help the conductor of a Salvation Army brass band performing "God Rest You Merry, Gentlemen" at the market collect money in his bucket; in doing so, he catches a young pickpocket with a wallet in his hand and forces him to surrender all the items he stole, include cash and jewellery (notably, Bean retrieves a ring the boy hid in his mouth by smacking him on the head). Bringing these to the conductor, who secretly decides to check out what he brought back (implying that he is greedily stealing the goods rather than donating them), Bean finds himself conducting the band, and has some fun with them, before having them conduct the same song with an upbeat, jazzy feel to it, earning a big round of applause from the crowd. With the conductor now back, Bean attempts to buy a Christmas tree from a stand, only to get to the stand just as the last two trees are bought. Frustrated and wanting a tree, he cuts down the market's large tree and attaches it to the roof of his Mini and drives home with it, with everybody at the market oblivious to the theft.

Act 2: Christmas Eve

Back at his flat, Bean leans out his window and pushes the rest away upon having set up his stolen Christmas tree with his new lights and his bauble, letting it crash onto the street below. He then sets up three stockings in the room – one for Teddy, one for himself and one for a tiny mouse living in a hole behind some furniture – before writing a few cards (all of the same design) and sealing them in envelopes, then stepping outside and posting them to himself. Satisfied with his decoration, Bean searches a cupboard for some Christmas crackers, but is underwhelmed by the lack of a loud pop from one, and so decides to take out the fuses of the other crackers and stuff them all into one to make a "super cracker".

Warming up his flat with a fire, enjoying a box of chocolates and drinking a glass of sherry, Bean tries to find something good to watch on TV but only finds war and horror shows. As he turns his TV off, he hears muffled singing coming from his door, whereupon opening it he finds a small group of young carol singers performing "Away in a Manger". Deciding to watch them perform from his seat as if he was watching TV, Bean soon becomes bored and rudely shuts the door on them just as they finish the song before heading for bed.

Act 3: Christmas Day

The following morning, Bean wakes up excited to the fact it is Christmas morning, and proceeds to check the stockings – his turns out to be a sock of his filled with the other; Teddy's turns out to contain a tin that holds a pair of button eyes within; the mouse's turns out to have a piece of cheese that Bean immediately places onto a mousetrap.

Bean soon gets to work in the kitchen on preparing the large turkey he won at the market, but while stuffing it, his watch comes off and gets lost inside. Unable to find it, Bean sticks his head into the turkey, whereupon he finds himself unable to pull it off just as Irma arrives. After attempting to cover up his predicament from his girlfriend, Irma eventually helps him to remove it allowing Bean to recover his watch but at the cost of the turkey as it is accidentally thrown out of the window in the process.

With the turkey gone, Bean and Irma instead eat cranberry sauce sandwiches along with carrot slices for dinner, whereupon Irma refuses to give Bean his present until she gets a Christmas kiss, only for him to outsmart her and rudely snatch it, ignoring her anger as he finds it to be a model ship. Realizing he is being forgetful, Bean produces Irma with her present, only for her excitement to turn into confusion and disappointment when he reveals that he bought her the portrait in the jeweler's display, believing it to be what she really wanted. Seeing her crying, he reveals the he "forgot the main bit", and produces a ring box, which she finds not to contain the ring she wanted, but merely a hook for holding the portrait. An upset Irma angrily storms out of the flat, leaving Bean puzzled and muttering to himself "What was wrong with it?" Realizing that she cannot pull his super cracker with him, he decides to do it himself, saying "Merry Christmas" to himself and as he does so, the act cuts to a view of his window from the street, along with a banging sound and a sudden white flash.
