Héroes Invisibles

This is a hard core humane series, very much worth watching as character building in historical series are usually quite weak.

Finns are on the other hand very good at character building in serious productions, unlike their Swedish neighbors, who are better at making mainstream entertainment productions suited for easy watching.

So it's absolutely NOT an action series although it's made in the Nordics. The Chilenian history is familiar in Finland and these events are well represented in the series.
