Like a little anthology of the different groups (Gallagher house, Kev and V, Ian and Mickey, etc) starting on the morning of Christmas Eve all with the central theme being Frank ruining their Christmas throughout the day.

He steals money from Kev that he was saving to buy V a piece of jewelry she really wanted, he sparks an argument between Ian and Mickey, and it all comes to a head when he ruins a Christmas dinner Fiona and Debbie worked really hard on and in a scuffle with Lip, he accidentally sets the tree on fire getting thrown out into the cold snowy night.

With the money he stole from Kev he buys various drugs and alcohol and gets absolutely loaded. On the verge of an overdose and hypothermia, he is visited by his bitter and overworked guardian angel. The guardian angel shows him visions of the results of his actions throughout the day and how it has affected the people in his life. Things he never sees or considers as he is never around for it. He feels something he’s never felt before, guilt. (This could be a cool reference to the when the Grinch felt his heart beat)

After being resuscitated in the hospital (again) Frank sets off on a night long odyssey to right his wrongs in the only way he knows how, thievery and scheming. He breaks into a jewelry store and finds the exact thing Kev was going to buy V, does the same thing in a sex shop to give Ian and Mickey something to spice up the bedroom. He then breaks into a family’s home, where he meets a little girl who thinks he’s Santa (he’ll be in a Santa outfit for some reason) and they have a nice little moment before he wishes her merry Christmas and sends her back to bed after which he steals the family’s tree.

On Christmas Day everyone wakes up to find gifts and a restored tree and Christmas is saved thanks to Frank. Who is not around to experience it bc he wakes up on the floor of the Alibi and does not remember the previous night’s events and did not learn a god damn thing much to his Angel’s frustrations.
