Otis ()

There are two children – 13-years-old Sofi and her brother, 10-years-old Hugo – living away from civilization, in an old, rusty ship stuck in the cliff. Having the ocean underneath and the forest behind, living their daily lives and taking care of each other, as siblings do. That changes one day, when children find a robot which somehow ended up in front of their door after a big night storm. The robot is out of battery, but once they figure out how to power it on, they find out that their destination is the same place: a utopian city called Ekk, where they think their lost mother is waiting for them.
