August 13, 1961: A fateful message reaches the train bound for East Berlin: The construction of the Wall has begun. The passengers now have three and a half hours to decide—home or freedom?

In the inter-zone train to East Berlin, people listen to the distressing radio reports. At the same time, we get insight into the lives of other people on this August 13, 1961 - the day when the Berlin Wall is erected and begins to separate its residents from the rest of the world.

The pressure on the train passengers increases as the train gets closer to East Berlin. Political views and personal desires and fears differ greatly, making it very difficult for couples to reach a decision.

The train is approaching Bamberg, causing the passengers to speak frankly with one another. Gerd is standing in the corridor and Marlis is sitting in the compartment. What will he decide?

The investigator Arthur gets one step closer to uncovering the secret behind the mysterious substances found in the baby carriage. Train driver Edith and Kurt, the cameraman, are also getting to know each other better.

The imminent division of Germany is marked by deeply personal moments centered on love, freedom—and a little promise that can mean the world.

In the end, only love remains, as can be seen in this part. Particularly during a final song performed by the band, a few tears are shed as the reality of the situation sets in.

Just before reaching the final stop in the West, Rudolf opens up about the past he has tried to forget. Sabine, the gymnast, makes a brave decision, and Sascha remains on the train without his friends.

The impending farewells now become an unchangeable reality at Ludwigsstadt train station, the last stop before the border.

Sascha confronts Rudolf, but he gets no certainty regarding his suspicions. Just before crossing the border into the east, one more person decides to leave the train.

With Edith having abandoned the train, there is a short wait just in front of the East German border, giving Anna and Sascha time to reconsider.

These days, a lot of people are paying attention to their carbon footprint. Drinking straws are no longer made of plastic, toothbrushes are made of wood, and we're happy to forego that domestic flight to Munich for a long weekend—all for the sake of the environment. But there's one person who doesn't care: Felix, a rabbit from a children's TV series.

Jannika from "ZDF Magazin Royale" has to give Felix the Rabbit a piece of her mind. All of his traveling is no longer sustainable given its impact on climate change!
