It is a snowy day, but Thomas does not want to wear his snowplough. So he tricks his driver into saying his snowplough does not fit and has to be removed. He leaves it on a siding and pretends he does not know where it is when asked by Emily when he returns to Tidmouth Sheds that night.
The Fat Controller has no choice but to leave Thomas in his shed and send Emily out to clear the tracks on Thomas' branch line instead. At first, Emily is angry to have to clear the snow, but after seeing children playing, she changes her mind. She clears the tracks in no time and when she reaches Dryaw Station, the Fat Controller lets her take Annie and Clarabel along the branch line.
When Thomas sees Emily having fun in the snow and taking Annie and Clarabel out, he feels like he is missing out the events. Thomas decides to try and find his snowplough so he can join in with the fun, but as he steams along the snowy rails, he discovers the sidings had not been cleared yet. He cannot find his plough so he decides to try and find Emily instead to join the fun or see if she found his snowplough at least. But it begins to snow and very soon, he gets stuck. Emily, however, uncovers his plough and soon finds Thomas in the drift. The Fat Controller is cross that Thomas hid his snowplough. Emily told him that they found it, and she rescues Thomas and gives him his snowplough.
Thomas learns his lesson and promises he will always wear his snowplough during the winter. The Fat Controller makes Thomas clear the snow for Emily the next day, but Thomas is not disappointed. Emily brings him to the slope where the children are playing to enjoy the snow.
