The crew welcomes the departure of Greenwood, but their new guest comes as a surprise. With the reappearance of the forceful Ulrich Wrangel, there is now a second captain on board, which quickly divides the crew. With an unhappy Tennstedt, a power-hungry young crew, and an undermined captain, a battle of loyalty ensues. Will the crew make the right decision?
Meanwhile, Carla and Simone’s relationship continues to develop, and yet they still have some clear differences of opinions. As Carla tries to convince her that there are sacrifices to be made in the battle for power, a level-headed Simone is finding it difficult to agree.
As Sinclair, a British resistance fighter and old acquaintance of Carla’s, arrives at the safe house, the team begins to plan their next attack. They don’t realize that they are more vulnerable than ever as Forster begins putting together the clues that lead him to Carla.
And as Forster makes his romantic intentions known to Simone, she is caught between her feelings for Carla and her duty to her job. But could she use both to her advantage?
