Secrets We Keep Ending Explained

The series starts with Cecilie having a normal night at home. She has an au pair, Angel, who is part of her family. Her son Viggo loves her very much, more so because Cecilie has been emotionally absent in his life. They are then visited by Ruby, who is their neighbour’s au pair. Cecilie and Katarina are close friends, as are their sons, Viggo and Oscar. As Katarina and her family are about to leave, Ruby, who looks tense, approaches Cecilie and asks her for her help in leaving her job. However, Cecilie asks her to talk to her host family to come to some sort of compromise.

The next day, she gets the call that Ruby is missing. Thinking the worst, she is immediately concerned, questioning whether it was Rasmus who is after this sudden disappearance. Rasmus and Mike work together, and the latter asks Cecilie to keep her thoughts to herself since she has no proof. However, she goes ahead and snoops around, finding a pregnancy test in the neighbour’s trash. Suspecting something bad is happening, she begins to question everyone around her, including her husband.

As the police get wind of this, they also start to question everyone, and, against her husband’s wishes, Cecilie goes to Alicia to tell her about the pregnancy claim. She is convinced that Rasmus might have raped Ruby and then killed her when she realised that she was pregnant. Considering Ruby was a devout Catholic, she would definitely have refused to have an abortion, leaving Rasmus in a mess.

Elsewhere, Oscar, Viggo and some of his friends are in a “locker room” type chat room where they share sexual and pornographic images of women. Oscar is clearly the ringleader while the others try to force a more innocent Viggo to partake in the immoral activities. On the other hand, Cecilie comes across texts between Ruby and Mike that send her over the edge. With his past rape conviction coming back to haunt him, she decides to retract his alibi to Alicia, leaving him to be questioned by the police.

In the meantime, the police find Ruby’s body in the water and positively identify that she was pregnant. They test Mike’s DNA against the fetus, which comes back negative. With nothing to go on, Alicia tells Rasmus the update, who also agrees to a DNA test to get the police off his back. Unfortunately, that test comes back 24% positive. Meanwhile, Oscar shows a video of him raping Ruby to only Viggo. He tries to tell Cecilie and Angel, who are overwhelmed with their own issues and don’t pay him any heed.

As a last resort, he tells his teacher about the text chain, which results in an enquiry, and Oscar is asked to be expelled. This also results in Cecilie and Katarina having a falling out. Eventually, Viggo comes clean to her mother about the rape. At her home, Katarina decides to check the nanny cam and finds the video of her son raping Ruby and decides to delete it. With the evidence gone, there’s nothing that the police can do without Viggo’s testimony. Unfortunately, Mike warns Cecilie to put their son through more trauma since it’s his words against Oscar and his family.

In the aftermath, the case is closed for lack of evidence, and before he is sent off to boarding school, Oscar tells Cecilie that Katarina had a falling out with Ruby the morning after the incident, which goes against her testimony. Cecilie confronts Katarina with this information, who doesn’t confess to anything, but says enough to prove that she knew about Oscar and Ruby and had killed her to help Oscar. The last scene shows Cecilie looking back in disbelief at everyone around her, unsure about where she stands in life.
