In the lush grove, six innocent boys and girls, each with their own concerns, play happily. Until one day, the angelic and cute "Menma" Meiko Honma (played by Tani Kanon) died unexpectedly, casting an indelible shadow on the hearts of other friends. Many years later, the friends gradually drifted away, and Sukumi Jinta (played by Murakami Nijiro), who felt deeply guilty about the incident, locked himself in his home. For some reason, Jinta suddenly saw the figure of Menma (played by Hamabe Minami) when he grew up. He told this to Hisakawa Tetsudo (played by Takahata Yuta) who met by chance. The Tetsudo was very excited and quickly gathered other friends such as Matsuyuki Shu (played by Shison Jun), Anjo Naruko (played by Matsui Airi), Tsurumi Chiriko (played by Iitoyo Marie) to find out Menma's unfulfilled wishes. But can the friends with scars in their hearts get back on the road together? This film is adapted from the animation of the same name.
