Plot
In the late 1960s, two young brothers in Sydney escape a violent household with their mother Kat by stealing the family car as her partner sleeps. They cross the continent with the intention of hiding out and making a new start in distant Albany, Western Australia.
Arriving south of Perth on the West Coast, they spot a perfect surf break and convince Kat to settle instead in a caravan park in Seacliffe, and the kids attend a local school while their mother does piecework as a seamstress.
Years later, in 1972, they are young adults, living with their mum in a run-down house she bought by the beach. Older brother Andy works in a timber mill while surf prodigy Jimmy wins the 1972 Seacliffe Amateur surf title - but away from his sport, he is listless and involved in petty crime.
Determined to escape their lack of prospects, headstrong Andy and his brother form a volatile alliance. Andy sees a gap in the market and fashions custom-made wetsuits sewed by Kat, and new short surfboards in their backyard garage, eventually attracting some sales, although they are refused a bank loan to develop the business.
JB, an infamous itinerant surf filmmaker, and Lani, his Hawaiian companion, drive into town in a converted school bus towing a Mini Moke. The brothers start a business called Drift, and their troubles with a drug-dealing biker gang begin to escalate.
JB embodies the era's anti-establishment vibe and is skeptical of Andy's interest in expanding his business, but soon realizes if the brothers can survive and stay true to their surfing roots, they might be part of something greater.
The fledgling business generates a powerful buzz amongst the hard-core local surfers, but when shooting publicity shots, Jimmy is towed onto a huge wave at a surf break called "the Morgue." Tensions arise as their boat capsizes and JB's expensive waterproof camera is lost.
The brothers’ progressive ideas further annoy the conservative locals and particularly the police, and they also find themselves embroiled in a violent feud with the bikers. The gang leader, Miller, uses a heroin-addicted surfer, Gus, to import kilos of heroin concealed in an order of surfboard blanks to the Drift surf shop.
But the drugs are discovered by the brothers and flushed away by Andy, imperiling their and Gus's lives when the gang discovers that they have no product and a large debt to suppliers. Gus, after trying to quit drugs, commits suicide by paddling out into the surf. Andy's growing relationship with Lani causes some friction between the brothers and with JB.
The town hosts a pro surf competition, which Andy enters with the intention of using the prize money to pay the bikers back. But Jimmy, a better surfer, returns from a period of introspection (where he was also hiding out from the gang, fearing for his life) and replaces his brother.
Jimmy gets to the competition final with a Hawaiian pro. In the last 60 seconds Jimmy, who is losing points, catches a huge wave, surfs a long barrel, and is photographed by JB (who has located and fixed his camera) doing a hands-off aerial. He then wipes out, getting injured on an underwater reef, and loses the competition after he is saved by Andy.
Without any money to pay the bikers, Kay agrees to sell the family house to the bank manager for a low price. The brothers drive to the surf shop and discover it is packed with customers, looked after by Lani. This business was brought in by JB's photo on the front page of the local newspaper, with the headline 'The future of surfing'. With money suddenly rolling in, Andy rips up and burns the house sale deed in front of the banker.
Jimmy is invited to join the world pro surf tour. He reluctantly agrees to go and discover the world, encouraged by JB, who lets it slip that Miller, the leader of the biker gang has been arrested - JB secretly planted Indonesian hash in his house and tipped off the police. Andy, Lani, and Kat wave as JB starts his bus and drives out of town to unknown future surf breaks.
