Three Maori youths, bored with Auckland, head south in a restored Mark II Zephyr in search of something different. One of them is on the run from drug dealers, whom he had crossed. Various mini-adventures occurs as they make their way down the North Island, but it all comes to a head while visiting a cousin. Finally, they, the drug dealers and the police all come together, with the expected fights and arrests.

Willie, a likeable kid, forms a friendship with Rikki, a new arrival at the reform school. Willie discovers that Rikki is maybe tough enough to take on Karl, the kingpin. Although Rikki is strong, he does not like to fight, but tensions mount as Karl's bullying become more obnoxious. After being shown up by Willie, Karl loses his temper and gives Willie a thrashing. As a result, Willie joins with some other boys in an escape. They steal a car, get drunk, and have a serious accident. Meanwhile Rikki is in hospital, injured in a forestry "accident' engineered by Karl.
