Queen City Rocker (1986)

In the turbulence of Auckland, Ska (Hunter) is a streetwise 19 year old, whose father is a drunkard and whose older sister works at a high-class massage parlour. When he decide to “rescue” her, he is thrown out. With some friends, he take revenge by trashing the place, but the reply results in Ska's best friend being killed. The massage parlour boss is also a crooked concert promoter, so Ska, and his gang, “hijack” a concert which incites the audience to riot.
