When Milo, a small mouse from New York City, meets Francesco, a chef at The Tall Skies Restaurant inside the World Trade Center, an unexpected friendship begins to bloom.

Milo is drawn to the bountiful food Francesco leaves behind, making frequent visits to the restaurant. Though he has explored many other places in the city, something always brings him back. More than just the food, it is Francesco's warm and welcoming nature that makes Milo feel at home.

By day, Milo scurries through the streets of Manhattan, exploring the city and keeping his belly full, all thanks to Francesco. But one fateful day, on September 11, 2001, in downtown Manhattan, Milo's world changes forever.
