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.
S.mouse, the U.S. rap artist who became an overnight sensation with his child-friendly single 'Slap My Elbow' has found himself under house-arrest and under pressure from the record company over his self-penned YouTube released 'Poo On You'. That very same song encouraged Nathan, half a world away, to make a tribute video that in turn has angered the local Dunt police. The authorities have been called and it seems Nathan is being sent away from the family to a deaf school in Adelaide. A new inmate arrives at Garingal. Gran takes Talib, the 'dog wanker', under her wing.
Daniel is organising a send-off for Nathan, 'Nathan's Legendary Farewell Party' before he leaves for deaf school. He plans to invite all the Legends from his 'Wall of Legends' to the party. S.mouse, the US rapper under house arrest and recently dropped from his record label because he uploaded his own composition and video 'Grandmother F*****' and ex-world champion surfer Blake Oakfield, now a washed-up surfie living in Narmucca Bay with his family but still involved in the surf gang, the 'Mucca Mad Boys' who have held the 'Fennell Hell Men' as rivals since they were children.
Tim Okazaki is a teen, gay, Japanese skateboarder who is a huge star in Japan, except we soon discover he's actually American, speaks with a fake Japanese accent, and is not gay at all. It is his manager-mother, Jen Okazaki, an all-powerful figure who has merchandised and marketed Tim into worldwide popularity with his catch-cry 'I'm Gay'. Meanwhile, Blake Oakfield's laid-back beach lifestyle is threatened by his wife demanding he pick up the groceries, and the Fennel Hell Men wanting to surf at Mucca Mad Boys' break. Meanwhile, Daniel is trying to organise the ultimate farewell party and stop Nathan from obsessive masturbating.
