Preskovitch who lives in the same building and always turns up unexpectedly to offer them various unappetizing pastries and Josette, a heavily pregnant woman on the run from her violent fiancé Félix. Félix is working as a Santa Claus during the season and turns up on her trail in costume and brandishing a gun. Félix and Josette, a caricature trailer trash couple, end up struggling over the gun and accidentally shooting dead the lift repairman, whom they then butcher and feed to zoo animals.
