The trainees are learning how to use their snowploughs, snow horns and snow lanterns, but they have yet to experience real snow. When a blizzard comes in, it's all chuggers to the rails! Wilson goes out with Harrison, promising to stick very close to him. Unfortunately, he gets distracted by some children building a snowman and falls behind.

The snowstorm worsens, so Wilson ducks into a tunnel to find shelter and an avalanche traps him. Wilson remembers what he learned that morning and uses his snow lantern and horn to attract Harrison's attention. Harrison isn't able to free him on his own, but when they use their horns and lanterns together, Action Chugger sees their signal and swoops down to rescue Wilson and fly him home.
