Sky has released the first look trailer for the third series of multi-award winning Sky Original drama ‘Das Boot,’ as well as announcing the commission of series four which will begin production in June.

The series follows the tense struggles of a young U-boat crew as they engage in the Battle of the Atlantic whilst being hunted down by an obsessed Royal Navy Commander in a thrilling game of cat-and-mouse. They are sent on a dangerous mission to the Southern Hemisphere under the command of Robert Ehrenberg (Franz Dinda) who finds redemption and the family bonds he thought he’d lost forever.

Meanwhile, in the climes of neutral Lisbon, where exiles, spies and criminals rub shoulders with allies and enemies alike, Hagen Forster (Tom Wlaschiha) discovers a lethal plot to steal a fortune in plundered wartime gold. This discovery and dark experiences on the Eastern front lead him to question his own actions and moral path and lead him to a shadowy figure caught up in a conspiracy that might change the course of the War – for the better. That man, much changed by his own shattering experiences, is Klaus Hoffmann (Rick Okon).

The drama takes us to Northern Germany’s Kiel, the major naval base of the German Reich for the first time, with each historically based strand leading to an epic series finale.

The 10-part series also sees Tom Wlaschiha (Game of Thrones), Franz Dinda (The Cloud), Rick Okon (Tatort), Pierre Kiwitt (Lobos sucios), Leonard Scheicher (Finsterworld) and Robert Stadlober (Summer Storm), reprise their roles.
