While testing out his camera on a bridge one summer night, Kaito sees a blue light streaking across the sky, only to be blown off the railing seconds later. Just before succumbing to unconsciousness, a hand reaches down to grab ahold of his own. He woke up the next morning wondering how he ended up back in his own room with no injuries or any recollection of the night before. As he proceeds with his normal school life, Kaito and his friends discuss what to do with his camera, finally deciding to make a film with it over the summer break. Noticing that Kaito has an interest in the new upperclassmen Ichika Takatsuki, his friend Tetsurou decides to invite her, as well as her friend Remon Yamano, to join them in their project. In what becomes one of the most entertaining and exciting summers of their lives, Kaito and his friends find that their time spent together is not just about creating a film, but something much more meaningful that will force them to confront their true feelings.
