The ship sets out from Fremantle, heading for Antarctica. The girls interview crew members, peel potatoes, and get training to improve their stamina. But as exhausted as they are already, an even greater disaster awaits them!

Expedition member Toshio confesses his love for Gin, and asks if Shirase knows anything that might help him get closer to her. Shirase tells him that Gin was just a friend of her mother's, so the girls insist that Shirase go to talk to Gin herself.

At last, the girls have arrived in Antarctica, and are awed by the scene before them. No one's been at Syowa Station in three years, so there's a lot to do to get it cleaned up. As the girls keep themselves busy, Yuzuki seems to make up her mind about something.

Kimari wakes up to the sound of her alarm and goes through her duties for the day. The girls have gotten used to their lives in Antarctica, but the summer team will have to leave in three days. Their journey of a lifetime is reaching its end.
