As they climb the Gran Paradiso, tempers fray, the risk increases, and one very frightening incident occurs...

The group has reached the hut where they are to spend the night. But the innkeeper has a surprise in store for his new guests, and not everyone is amused.

It's nighttime in the cabin, and people appear to be in high spirits until Wolf starts dancing with Lisa...

Mark and Wolf reveal to each other how they got into their respective situations, Rosi is in love, and Rocky surprises everyone with his engineering skills.

The group gets caught in a terrible storm and emotions run high as some start to give up all hope of finding the bivouac... Luckily, Mark knows what he's doing.

Having been caught out in the storm and in desperate need of shelter, the two hikers from earlier suddenly burst into the bivouac. They prove themselves to be as disrespectful as ever, and Wolf decides he isn't going to stand for it...

The next morning, it's clear that Wolf has run away. Martin is adamant about following the rules and intends to break off the expedition. Lisa tries to convince him not to do that so close to the finish.

When the group learns who is responsible for Wolf's escape and, therefore, for the fact that the expedition has to be called off, everything gets out of control.

Will Mark and his companions continue their ascent? They get an unpleasant surprise that could jeopardize everything...

Ben notices a few odd circumstances surrounding the death of Jannik Sternberg, while the cops at the station continue to try to impress Nicole, their new colleague.

Too many things about Jannik Sternberg's death seem odd, especially when the colleagues find out that this isn't the first "accident" at the construction site.

In this episode, the police find more evidence that Jannik's brother-in-law, Mr. Nagel, may have been involved with his death.

The officers investigate an unlikely break-in as the case of Jannik Sternberg becomes increasingly more suspicious.

The construction site where Jannik Sternberg fell to his death comes under scrutiny. At the station, Dirk and Lothar realize that Nicki might need a bit more supervision.
