Well in the movie there is a field mouse mother who son gets sick. and she goes to find a cure for him and goes through this weird adventure and i remeber a weird owl and weird creepy rats god its so frustrating that i cant think of the name of the movies....
in the beginning the humans were doing construction and it was right at the field mices house ....
