In the once beautiful and spacious countryside of a farm, a fatherly sparrow named Passer is surprised to see yellow monsters appearing around Farmer Henry's home. Passer, fearing the worst, decides to embark on a journey to learn if his family is in danger. When the wise neighborhood owl, Ash, tells Passer that his home is threatened by human development, Passer must race against the clock to return home and save his family from impending destruction. Along the way he befriends a crow with a tragic backstory, meets other animals fleeing the destruction of their homes, and fears for his generational friend, Birch, an ancient tree that has stood guard over the farm for hundreds of years.
