In a near-future Australia, the economy has collapsed and crime surges through the inner cities. The manufacturing sector has withered to the point where cars are a scarce commodity, and salvaging parts has become a shadowy trade between rival gangs and scavenging companies. With only Australia, the United States, and North Korea left standing as functional nations, the government tries a drastic approach to curb the violence: seize a chain of drive-in theatres and convert them into concentration camps for the undesirables and unemployed youth. The camps are fenced off, the entrances guarded, and the surrounding roads—boldly labeled Security Roads or “S-Roads”—are electrified to deter any attempt at escape. In a brutal twist, police collaborate with drive-in owners to sabotage visiting cars, while a few inmates end up seeking shelter, food, and a fragile sense of safety inside these decaying havens.
Jimmy "Crabs" Rossini [Ned Manning], a young fitness enthusiast, slips away in his brother’s vintage Chevy to take his girlfriend, Carmen [Natalie McCurry], to the local Star Drive-In. He claims they’re unemployed to secure a discounted rate, hoping for a simple night out. But once inside, Crabs discovers that the drama of the outside world has followed them in: a chain of misfortunes begins with the rear wheels being stolen, and he soon learns that the police themselves are responsible for the sabotage. The drive-in’s owner, Thompson [Peter Whitford], pretends to file a report and then enrolls the couple into the camp system, making it clear they’ll be stuck there for the foreseeable future since buses and cabs are non-existent. He even hands them meal tickets for the camp’s rundown café, a reminder that life outside has become a luxury no one can rely on. Time crawls by, and Crabs’ repeated attempts to escape are thwarted at every turn.
Crabs grapples with the electrified fence and discovers his fuel tank has been drained. He manages to siphon fuel from a police vehicle but finds that his engine has been stripped. With mounting suspicion that Thompson—the man who profits from every new prisoner—might be pulling the strings behind the sabotage, Crabs warns him that interference won’t go unchallenged. The tension is heightened by clashes with a racist gang that patrols the camp’s edges, adding a volatile layer to Crabs’ already precarious situation. Carmen, meanwhile, drifts further into the camp’s unhealthy culture: she befriends several other female inmates and, overwhelmed by the camp’s hopeless environment, begins to adopt the hostile, xenophobic mindset that blames non-white Australians for the country’s ills. The arrival of foreigners and illegal immigrants—brought in by a warming world that has made parts of Europe and Asia uninhabitable—exacerbates the anti-foreigner sentiment and solidifies the camp’s toxic atmosphere.
Crabs makes one more attempt at escape while a racist meeting draws most of the camp’s attention. He hijacks a tow truck and tries to slip away peacefully, but Thompson notices and a high-stakes chase erupts inside the enclosure. Automatic weapons fire from the police add chaos as fighters and civilians alike dive for cover in the café. Crabs crashes but survives, continuing the pursuit on foot. He finds Carmen again, pleading with her in a moment of attempted clarity, and even shares a lingering kiss before resuming his bid for freedom. In a bold move, Crabs disarms Thompson and forces him to remove the prisoner from the government server, cutting off the financial incentive that underpins the camps. Yet this struggle ends in tragedy: Thompson is killed in the ensuing confrontation, and a determined police officer closes in on Crabs.
With the odds stacked against him, Crabs makes a final, daring leap. He uses the lowered ramp of a police tow truck parked near the camp’s entrance to launch a vehicle over the fence and onto the S-Road, escaping the camp’s confines and driving toward an uncertain but real freedom beyond the electrified barriers. The story lingers on the fragile thread of hope as Crabs drives away, leaving Carmen behind to confront the consequences of a world that has traded humanity for order, while the road ahead remains perilous and undefined.
