A group of Venturer Scouts and their leader battle Russian Mafia to avert millions of dollars in recreational drugs hitting the streets of every Australian capital city. The Venturers go on their annual Christmas holiday camp for a week of surfing, canoeing and pure fun. Russian drug Mafiosi arrange for a mother ship to drop off a cargo of drugs in a wrecked former Navy submarine near the boys' campsite. The Russians take the Venturers prisoners after they find the drugs leaving it to the most unlikely youth to escape and turn a lighthouse into a weapon against the Mafiosi.
