''Summer Time Machine Blues'' is based around a group of friends in a science-fiction club who spend their days fooling around at the clubhouse. The boys play a game of baseball as their friend Yui Ito takes pictures of them nearby. After the game, the boys return to the clubhouse and head off to the bathhouse leaving the girls, Yui and Haruka to develop their pictures. While they bathe, Niimi gets angry because he thinks someone stole his Vidal Sassoon shampoo. On their way back, Komoto decides to sneak off to buy tickets at the theater for a sci-fi B movie. He hopes that he can ask Haruka out. Haruka says that she does not want to go out with him since he apparently has a girlfriend, but Komoto has no idea what she is talking about. But when he returns to the clubhouse, his friends act very strangely as to where he has been. They make him explain what happened, but through a series of chain events, Ishimatsu accidentally spills Coke all over the air-conditioner remote control after being hit in the face. Everyone rushes to try to clean the remote off, but it's too late. The remote is broken and they cannot turn on the air-conditioner. This immediately becomes a problem as the day becomes hotter.
