What a day Alexander is having. He's got gum stuck in his hair, he trips on his skateboard and he can't find his favorite glow-in-the-dark yo-yo. Things go from bad to worse in this charming animated musical based on the book by Judith Viorst.

A reporter, fired after refusing to give names to a 1951 House Un-American Activities Committee, takes a part-time job as companion to an old lady. While working she overhears a noisy argument in the neighboring house, being conducted largely in German and involving her HUAC prosecutor. She begins to investigate, enlisting the help of the FBI Agent initially detailed to surveil her.
