High school students in their prime time are forced to grow up pure, honest, and sexually upright in Catholic high schools. Hypocritically, however, they spend time knowing that the reality they will face is not so. Several large and small incidents, such as a friend who made a mistake with feces during a performance, a situation in which he has no choice but to hang out with bad friends, and a boy who wants to prove his masculinity, are put with a stop motion technique that is partially colored one by one in 30,000 originals photographed in black and white. Director Karl Glenn Barit has won at several film festivals for his short films dealing with migrant workers, the socially underprivileged or marginalized people left outside of a big city. Cleaners is his first feature film. (PARK Sungho)
