Das Boot season 3 plot

In Das Boot season 3, the young German U-Boat crew, under the command of Robert Ehrenberg (Franz Dinda), are in very dangerous waters as the British Navy has started to get to grips with the relentless German attacks by using ever more sophisticated sonar technology and depth charges. Despite this new peril, the German sub is sent on a risky mission to the Southern Hemisphere where Ehrenberg gets a shock as he finds redemption through family ties he thought he’d lost forever.

Into the sea battle, however, arrives a new British naval commander, Jack Swinburne, played by Ray Stevenson (Rome, Thor, Black Sails). Formerly a captain in the merchant marine, Swinburne is now in command of HMS Perseverance. After his son dies in a German submarine attack, something shatters inside him and he becomes embittered with deep grief. He then dedicates his life to just one thing — total revenge on the German subs responsible for his family tragedy. He’s certainly up for the ceaseless cat-and mouse chase with Ehrenberg.

As always with Das Boot, the action plays out on land too, in various different locations. So this 10-part series, for the first time, heads to Kiel, the major naval base of the German Reich. There’s big intrigue in neutral Lisbon, where SS commandant Hagen Forster (Tom Wlaschiha) discovers a lethal plot to steal a fortune in plundered wartime gold. This and his recent dark experiences on the Eastern front lead him to question his past actions and moral path. He also meets a shadowy figure from his past, former German U-Boat commander Klaus Hoffmann (Rick Okon) who is caught up in a huge conspiracy. 

Hoffman is a much-changed man after his shattering experiences in the previous two series of Das Boot when he was betrayed by his crew and left for dead, only to be rescued from an American beach at the end of the last season. Could this unlikely duo pair up to do real damage to the Third Reich and possibly change the course of the war?
