On a hot summer day in Kyoto, a young man walks toward his apartment, dreaming of turning on the air conditioner and cooling down. But before he can turn his dream into reality, disaster naturally strikes in the form of Ozu, who spills soda all over the remote. With the air conditioner rendered completely unusable, the man and his friends are left to suffer in the terrible August heat.

Just when all hope seems lost, the group finds a true-to-life time machine in their storage room. Not knowing the dire consequences of doing so, they decide to travel back to the past and grab the remote before Ozu even has a chance to destroy it. What awaits them on the other side is a staggering adventure none of them are prepared for.
