Mats Kruger is terrified of flying. But his daughter, Nele, is about to give birth to his first grandchild, so, for once, he΄s taking the risk and making the thirteen-hour flight from Buenos Aires to Berlin.

Of course, he΄s taken precautions. He΄s bought the five statistically safest seats on the plane, as well as seat 7A - the spot where you are most likely to die in a plane accident - so no one can sit there. Just in case.

But Mats has to give up seat 7A to another passenger. Moments later, he receives a phone call. Nele has been kidnapped. The caller has a single demand.
