The film opens in the midst of a celebratory exhibition match in Ooarai. Darjeeling, in her Churchill flag tank, is hunkered down with four St. Gloriana Matilda tanks in a sandpit on a golf course. The vehicles of Ooarai Girls High School close in from all sides. Supporting Ooarai are numerous tanks from Chi-Ha-Tan Academy, under their commander, Kinuyo Nishi. The overall commander, Miho Nishizumi, observes the situation from atop her Panzer IV then orders everyone to advance. Amongst the spectators are several students from Jatkosota High School.
