Due to weather issues, a plane from Denmark was forced to land at Slovenia airport. Among the passengers who were taken to a hotel in Ljubljana was a quiet and beautiful young Danish girl named Ibn (25 years old). This is the way she met Tina (25 years old), who drove a shuttle car to do summer work. They all need each other, but they are very careful because one of them is hiding a secret. They talk to each other in English and their mother tongue. Only one of these two languages has the so-called duality, which is a special grammatical form used for expressions involving only two themes. Another language is not the case. Dual is an honest story that tells the story of two people meeting at a time when they absolutely shouldn't have met, but they are still a bit happy because they did it.
