A son quits his job and is persuaded by his father to head off to a cottage in the remote mountains. Together, the two of them manage to get through their days while wearing old jerseys left by a deceased grandmother. The following summer, the two once again leave the stifling heat of Tokyo, as if escaping to the mountain cottage. However, the next summer is very different.
