Mari Tamaki is a second-year high school student who wants to take initiative in something. She meets Shirase, a classmate with few friends who is often mocked and given the nickname "Antarctica" because she constantly speaks about it. While others dismiss her, Mari is inspired by Shirase's passion and decides to support her, even though it's improbable that high school girls will ever travel to Antarctica.
