Sandra Piazelli, a childhood friend of Emilie's, is visiting Ramsau and surprises her friend with a booked gorge hike. Yvonne Kern has also signed up for this hike. Is it a coincidence that she also shows up at Emilie's farm that evening as an overnight guest and is particularly interested in Sandra's new love, Johannes?

Markus wants to spend his day off with Alex and has prepared a special surprise for her on the mountain. But his plans come to an abrupt end when he is called out on a mission. Mountain guide Emil slipped during a tour and is about to fall into the abyss. At the last second, Markus is able to rescue him with a risky aerial maneuver. Since Emil is now unavailable for the gorge hike, Sandra asks Markus for a private tour for Emilie, Yvonne, and herself. A welcome distraction for him, allowing him to take his mind off his personal worries. The fact that Markus doesn't find enough time for Alex, partly because he is supporting Nina in her healing process, is increasingly taking its toll on their relationship.

His relationship with Tobi also remains strained, especially since Katharina surprises him with a demand he finds impossible to fulfill. When the connection between Sandra and Yvonne becomes clear on the tour, a chain of dangerous events begins, which also affects Emilie.

Winter has arrived in Ramsau, and the first avalanches are hitting the Dachstein. While Markus, Katharina, and Tobi are securing the southern slope, a snowmobile races through the restricted area. The driver loses control and threatens to plunge into the abyss.

The crisis between Tobi and Katharina, however, seems to be coming to an end. After a discussion between the two, Katharina's real estate agent Lukas Schlosser makes a suggestion that would solve all the problems in one fell swoop.
