After two weeks of knowing each other, a witless young New Zealander with a dodgy English accent agrees to go to a music festival in Cornwall... er, Ireland with a witless young Scottish guy. They take the ferry to Cornwall... er, Ireland and stop at a pub where the New Zealander sits on the toilet waiting for something to happen. Later, they get into their car and the Scottish guy announces that instead of going to the festival, they are going to a hotel and need to wait for someone to come and show them the way. A Land Rover pulls up behind them and then drives past with a hotel sign on the tailgate so the witless couple follow. Eventually the Land Rover stops and the driver points to the road ahead before taking a right turn and disappearing. The witless couple continue on and get lost. The Scottish guy is driving and starts to drink, while the New Zealander looks increasingly anxious. It gets dark and they car begins to run low on fuel. The New Zealander tries to follow a map but the Scottish guy keeps on drinking and tries to follow a confusing set of signs for the hotel. Then the Scottish guy decides to pull over and wander off into the forest for no apparent reason. The New Zealander gets even more anxious but the Scot returns and they both decide to wander off into the forest, leaving the keys in the car. They don't get far before the car alarm goes off so they return and can't find the keys, until they find they keys on the ground. They drive off and go around in circles until eventually someone tries to attack them and they flee, only to knock a guy over and then all hell breaks loose, but not in a logical way.
Given that the couple are utterly lacking in common sense, and spend most of the time shouting at each other and making stupid decisions, the viewer is left not really caring what happens as the story spirals down one plot hole after another. One day someone will make a movie about sensible folk who despite their best efforts journey into a nightmare. Sadly, this isn't it.
At least Downton Abbey's Allen Leech get's to chew some scenery!
