Looking for the latest Nordic mystery thriller (Netflix)?

I heard about a mystery thriller in which a son is looking for his father who did not return from a boat tour. And the son also returns from the search changed, because something scary is going on off the coast, or something like that. I read about it recently but can't remember where. Seems to be a current thriller from the Nordic countries. Does anyone know anything about it?

It is probably this film

The Block Island Sound (2020)

YEAH, this is the movie!

With pleasure.
