When Sam returns home to the tidal island where he grew up to attend a funeral, he soon discovers that the seedy underbelly of this small community harbours more than just a few secrets.

Darren, Lou, Jo and Mas live a meager existence on the fringes of poverty. Indebted to the criminal kingpin of their social housing development, they routinely fear for their lives. On the other side of town, the already wealthy Marcus and his disabled brother Clive receive a windfall in the form of a winning lottery ticket. When their worlds collide following a botched robbery, the would-be criminals get more than they bargained for, and will be tested to their limits in a desperate attempt to survive a predator of monstrous proportions.
