Ulrich goes looking for Mikkel in the cave — and discovers a sealed passage to the nuclear power station. Is there a connection to the disappearance of his son?
Jonas follows his father’s map to a shaft behind a rusty metal trapdoor. On the door is a mysterious symbol and the words sic mundus creatus est — so was the world created. Squeezing through, he finds himself in the year 1986. He had been guided to the shaft by the Stranger, who wanders through the cave, passing between the past, the present, and the future.
Later, Helge also travels through the cave to the 1980s to stop his younger self. Ulrich suspects him of being responsible for the disappearance of the children and follows him — but when he leaves the cave, he has arrived, not in 1986, but in 1953.
