Aaron and Mona embark on a wild adventure. But what is wild and what is truly dangerous? The prohibition against stepping on the lawn can be bypassed. And climbing a tree is simply enjoyable. However, when the children fish a bottle out of the river, they have no idea what’s inside. A man explains the danger symbols on the bottle to them. Oops! Such things are also found at home, in the cleaning cupboard, in the bathroom. In the midst of all the adventure, Aaron and Mona have forgotten to go to school, but now they know where it’s really dangerous.
