Josie, who lives in her own world, swims in the ocean of paintings and books that interest her. She has been sitting in a wheelchair since she was a child. One day, when she almost fell on a dangerous slope, she was helped by a college student, Tsuneo. Tsuneo, who specializes in marine biology, works part-time day and night to realize his dream of seeing the dream fish that only live in Mexico. Chizu, Josie's grandmother, saw Tsuneo like this and introduced him to a part-time job. The content of this job is to listen to Josie's requests and find ways to satisfy her. However, Josie, who is stubborn and not good at communicating with others, is very mean to Tsuneo, and Tsuneo does not care that Josie is disabled and responds to her straightforwardly. In this way, the distance between the two sides gradually shortened and they began to understand each other. In the process of the two people's contact, Josie also made up her mind to go with Tsuneo to see the outside world that she had always dreamed of... The film is adapted from Seiko Tanabe's novel "Jose, Tigers and Fishes".
