The members of a sci-fi club accidentally spill Coke on the remote controller of an air-conditioner during summer and suddenly a time machine appears in their sweating bath-like clubroom.
Summer Time Machine Blues is a 2005 Japanese film directed by Katsuyuki Motohiro and written by Makoto Ueda, based on Ueda's 2001 play of the same name. The film stars Eita as a member of a university science-fiction club, and Juri Ueno and Yoko Maki as part of the neighboring photography club.
