Gnome Alone is a 2018 CG animated film by Cinesite that centers around a centuries-old war between Gnomes, who protect the earth and "Troggs" whom would consume everything they can.

When high school student Chloe discovers that her new homes garden gnomes are sentient and their mission, she must decide between the pursuit of a desired high school life or taking up the fight against the Troggs.

This film has nothing to do with Home Alone.
