Winter has come to Manehatten, and while the Hearth's-Warming spirit is rearing its head, the cold yearns for the attention of all. It has been two years after the invasion on Canterlot. Since then, changelings have been flocking to Equestria for a better chance at survival after their crushing defeat--and a better life.

One of them is Frill Spike, a mail carrier that has been determined to earn enough bits buy a place of his own. Until then, he works hard to earn his keep. One day, an opportunity arises for him to earn extra pay by taking on another route. This route, however, will present a new challenge that he will have to deal with on a physical level and a mental one.

This route also includes the apartment building where Marsh Olive, an earthpony colt, lives in. He lives a repetitive, almost secluded life under the over protective eye of his father, who has been distraught ever since the Canterlot invasion that took his wife from him. Paranoid of the world and the changelings in them, he goes to the extreme when it comes to the security of his son. Marsh, however, wants security from the isolation such safety measures bring.

These two individuals have never met each other before. No one time in their lives have their paths crossed. However, the coming days will bring them together as they begin to fight against their personal issues. The question is whether or not they will be able to succeed in their battles, all the while the cold snare of Winter blankets itself on the city.
