The cast includes Rena Tanaka as Keiko Obayashi (the student) and Akira Emoto as Nabe-yan (the leader of the five men).
She wakes up in rural Masao, where she soon finds a job working in a newly opened convenience store.
Meanwhile, five middle-aged men who run local shops are worried about the competition from the new store, and plan to disrupt it.
The film follows them as they practice in secret, are found out by Keiko who agrees to coach them, and finally play a match against a lacrosse team from America who are attracted by the Native American nickname (Geronimo) of one of their players.
The men are heavily defeated, but Geronimo becomes a hero when he scores the team's only point, and the film ends with him flying to America with the Americans.
