Exploring what happens over one school term in an average Australian high school, this mockumentary brings to life Jonah, a 13 year old mischievous schoolboy from Tonga with the odds stacked against him; Mr G, an ego-driven drama teacher with delusional showbiz dreams; and Ja’mie, a private schoolgirl on a student exchange, set to make her mark on Summer Heights High.

Justin Tolchuk is a sensitive, lanky 16-year-old just trying to make it through the social nightmare of high school in Medora, Wisconsin. When his well-meaning mom Franny signs up for the school's international exchange student program, she pictures an athletic, brilliant Nordic teen who will bestow instant coolness on her outsider son. However, when the Tolchuk's exchange student arrives, he turns out to be Raja Musharaff, a 16-year-old Pakistani Muslim. It's going to be a very interesting year for Raja, Justin, his family and the entire population of Medora.
