The series kicks off in Dunt, South Australia, home to identical twins Daniel and his 90 percent deaf brother Nathan. They dam surf, they skate, they do 'mainees' in the street in their mother's hotted up Nissan Pulsar. In their bedroom are the 'Wall of Legends', pictures of the people they consider their heroes — surfer Blake Oakfield, Japanese skater Tim Okazaki, U.S. rapper S.mouse, bikini model Emily Chase, their late dad and their prison officer grandmother, 'Gran'. Gran lives and works at Garingal Juvenile Justice Centre for Boys together with her co-worker Penny. In her spare time, Gran cares for her 23 guinea pigs and makes superhero pyjamas for the young inmates.
