Plot: A couple buys a cheap self-assembly wardrobe which leads them to the fantastical, but slightly rubbish, land of Njarnia. Wrong Door viewers also meet unfortunate wannabe superhero Rocketman and the monster who lives in the office stationery cupboard; Philip the Dinosaur goes bowling; there’s an intriguing new weight-loss cure; and a water-cooler moment viewers probably won’t want to share
