Goodbye, Don Glees! (グッバイ、ドン・グリーズ!) is a 2022 Japanese animated adventure film produced by Madhouse and directed by Atsuko Ishizuka. It premiered in Japan on February 18, 2022.
Plot
When they were children, "Toto" Mitarai and Roma Kamogawa formed their own club, the Don Glees. When Toto reaches 15, he moves to Tokyo to attend high school. Toto returns a year later to find Roma longing for his crush, "Tivoli" Urayasu, who has moved away to Ireland. Toto goads Roma to contact Tivoli, even calling Tivoli long distance to get Roma to talk to her.
Toto also finds that Roma has added a new member to the club, "Drop" Sakuma. Drop talks Roma into spending all his money to buy a drone. They will use the drone to film a large professional fireworks display, while setting their own fireworks in a secluded field. But on the night of the display, they cannot get their fireworks to light, and Roma loses the drone. Some hours later, a wildfire breaks out in the mountains. The next day, their schoolmates spread rumors that the Don Glees set the fire, based on the police finding their dud fireworks. The three friends locate their drone, and decide to retrieve it to use its video footage to clear their names.
The drone landed in a place in the mountains so isolated that the kids need to hike overnight to reach it. To go, they lie about their plans, and dodge investigating police officers and bears. But they don't make it before sundown, and so settle down near a small waterfall. Drop tells the others about how everyone should have a "treasure" they should want more than anything else.
