Raised in a difficult family, meek and docile Nan spends most of his time caring for his ill grandfather and contending with his hoodlum uncle; his only refuge lies in the pure world of his favorite anime, Bobita. When Nan meets a girl who also loves Bobita, romance blossoms and then swirls beyond control, as his desire to gain her affections leads to trouble and even murder. High Flash director Chuang Ching-shen’s piercing sophomore feature delves into otaku culture, broken family ties and the mentality of the socially marginalized to explore what drives an awkward young man over the edge.
