What is the plot of January

The days are short,
The sun a spark,
Hung thin between
The dark and dark.

Fat snowy footsteps
Track the floor.
Milk bottles burst
Outside the door.

The river is
A frozen place
Held still beneath
The trees of lace.

The sky is low.
The wind is gray.
The radiator
Purrs all day.

I am not good with finding a plot so please help!!!

A plot is just a story. I don’t see a story in this poem.
