Five university students in North Queensland, Australia, spend one insane summer night tearing their share house apart looking for a hidden million-dollar scratch lottery ticket, as outside, a catastrophic tropical cyclone looms.

During one gruesome night at an isolated bar located in the furthest stretches of the Australian outback, the fun-loving staff go from drinking, partying, and negotiating sexual politics with each other, to fighting for their lives, as some evil force lurking in the cellar finally rises to the surface, and begins to leave a bloody, horrific trail of bodies in its wake.
