A young school girl discovers that she has the ability to traverse space and time. With her newly discovered ability to literally leap backwards in time Makoto finds that tests become a piece of cake, embarrassing situations are corrected, and she can have her favourite food anytime she wants. Unfortunately, her carefree time traveling has adverse effects on the people she cares for.
In her efforts to use the power as a means of preserving her closest friendships, the film becomes a poignant take on the perpetually shifting nature of personal relationships.
Originally based on a famous Japanese sci-fi novel by Yasutaka Tsutsui, this story has been made and remade into films, TV series and manga. This however, is the first time it has been told in an anime feature form.
