All seems to be well on a quick look, but underneath the surface the friendship between the trio is put to the test: Robin spends more and more time with the girl who arrived at the sanatorium in the spring and Vilma retreats more into her own world. The disturbing noises during the night are getting louder again and won't leave Oskar alone. The final piece of the map leading to the forest is finally found, and the children learn of a mysterious and life-threatening task. A task that only the three of them can complete.
