Three problem students (Dean, Duncan, and DJ Beatroot) are taken to the Scottish Highlands by teacher Mr. Carlyle to try to achieve the Duke of Edinburgh Award, which requires participants to navigate the Highlands as a team relying only on a paper map. The three are joined by the bookish student Ian, who wants to receive the award to improve his college application.
Carlyle drives off in the minibus, instructing the boys to meet him at a designated campsite. The boys reluctantly set out, but spirits rise when Dean reveals he has hash. Unbeknownst to them, a man watches through a rifle scope as the boys get high.
The boys encounter a farmer plowing his field. After getting directions from him, DJ Beatroot gives the farmer his mix CD. Sometime later the boys spot a man in upper class hunting gear and ask him for help, but as he nears they see he is wearing a mask and he begins firing at them. Fleeing, the stoned boys decide he must be the "Duke of Edinburgh." The bumbling Dean and Duncan manage to improvise a trap that improbably sets the "Duke's" leg on fire, forcing him to retreat.
The boys reach the campsite and find Carlyle, who has a burn on his right leg. Believing that he is the Duke and that he will kill them, Duncan sneaks to the minibus and runs Carlyle over. The other boys freak out, but they ultimately decide to make Carlyle's apparent death look like an accident by having the minibus drive off a cliff. However, after they put Carlyle's body in the vehicle, it starts rolling back down a long hill. Duncan says it will most likely fall off a cliff anyway and the boys continue on.
Meanwhile, the local police, Sergeant Morag and PC Hamish, interrupt their search for a notorious bread thief after Morag receives an erroneous report that Duncan is a terrorist and is loose in the area. They set off for the boys' last known location.
The boys then encounter the Duke again, who is joined by his equally insane sword-wielding wife, the "Duchess." The boys realize to their dismay that Mr. Carlyle was not the Duke after all. As they flee, Ian falls into a ditch and is separated from the others. DJ Beatroot then argues with Dean and Duncan and sets off for a barn in the distance while the other two head to a cave to ingest a load of powdered soup.
Inside the barn DJ Beatroot is shocked to find a large group of farmers who are big fans—the farmer he encountered earlier has been sharing his mixtape CD. He stays to party with them and holds an impromptu concert. Elsewhere, the Duke and Duchess capture Ian; Dean and Duncan, covered in powdered soup, hear his cries and rush off to help. Just as it looks like all is lost DJ Beatroot and the farmers appear and chase off the Duke and Duchess after stealing their weapons.
The next morning boys decide to hunt down the Duke and Duchess. They finally corner the pair on a shoreline. The villains, held at weapon-point, explain that modern youths must be culled because they are too bratty and ungrateful. Dean retorts that adults have wrecked the world and left young people to clean up the mess. Suddenly, more well-dressed, masked hunters join the Duke and Duchess, holding the boys at gunpoint. They prepare to execute the boys, when the minibus rolls off a cliff onto the hunters, crushing them all to death. The relieved boys look inside the minibus and are overjoyed to see that Mr. Carlyle is in fact still alive, if only barely. After makeshift medical treatment, the severely injured Carlyle springs up and says that the boys are in big trouble for trying to kill him. The police, Morag and Hamish, appear. As Carlyle tries to tell Morag about the boys running him over, Hamish discovers a huge stash of stolen bread in the back of the minibus—it turns out that Carlyle was the notorious bread thief. The boys cover for him by telling Morag that the van belonged to the crushed hunters. In gratitude Carlyle agrees to give the boys the Duke of Edinburgh Award and they are celebrated as heroes.
