The AK1 team hasn't had a holiday for months now. So, instead of sitting on call at home, Charly and Jenny decide to have a long weekend on the Canary Islands. But no sooner have they taken their seats on the plane, then they're back at work again. Three criminals have taken over the Ilyushin and are demanding the release of the diamond robber Karl Mendl from a Berlin prison. If their demands are not met, they threaten to make the plane and its passengers crash in the centre of Berlin.
While Charly and Jenny secretly try to call headquarters on their cell phone, Rubelli has the unpleasant task of informing Dahlberg why the two officers who were on call that weekend are now already at the scene of the crime. At first Dahlberg is furious but then he sees the advantages of this infraction of the rules.
Charly attacks one of the highjackers, but the others overpower him, knock him out and tie him up. Dahlberg has no other choice but to give in to their demands. He has Mendl released---but with a location transmitter built into his shoe. Then, to the horror of the passengers, the three highjackers jump out of the plane with their parachutes. Now the plane is heading at top speed for a crash landing in the centre of Berlin...
Jenny desperately tries to shake Charly awake because he is the only one who can land the plane. When Charly (still a little dizzy) sits down in the cockpit, there is a shock waiting for him. The steering apparatus is blocked. While Charly tries to repair the steering, Jenny has her first, very involuntary, lesson in flying an Ilyushin. After a successful emergency landing, Charly and Jenny have the pleasure of following the signal being sent from Mendl's shoe and then arresting both Mendl and the highjackers. But what about their holiday? Well, tomorrow is another day...
