Blood is thicker than water.

If you think Australian beaches are all about sun, surf and having a good time, then brace yourself for the extraordinary feature documentary Bra Boys.

This confronting documentary is set in the inner-Sydney beachside suburb of Maroubra and follows the social struggle of the tattooed and much maligned surf gang known as the Bra Boys.

The Bra Boys are the true-life Abberton brothers – Sunny, Koby, Jai and Dakota.

One is charged with murdering a Sydney standover man, another pursues a professional surf career but is charged as an accessory in his brother’s legal fight, a third is trying to hold the family together, and a fourth is drowning under the weight of his siblings’ notoriety.

This compelling, larger-than-life story is brilliantly narrated by Australian actor Russell Crowe.
