Treasure hunt on the estate (S01E02)

Nanna is tasked with taking care of Niels and organizing their rooms while their father checks out the family's new house in Næstved. Meanwhile, Niels, Charly, and Tania pull a fast one on Nanna and escape to the estate in search of treasure. With assistance from Johannes and Louise, Nanna tracks them down, but they soon realize they're not alone in their quest, as others are also on the lookout for the treasure hidden in the estate's basement.
