14-year-old Minke is found on the highway three years after her kidnapping. She doesn't know what happened or why she has wings tattooed on her back. Detective Asha, who failed to find Minke, is determined to unmask the perpetrators this time. Minke's father, ex-detective Lucas, conducts his own investigation against all the rules.

A gruesome suicide puts the investigation into Minke's kidnapping on edge. To speed up the process, police psychologist Kim tries to bring out Minke's repressed memories. Minke is also going back to school for the first time, but in her head she is busy with completely different things. Detectives Asha and Fenna investigate DuPont's past and grow closer.

After the accident and Kim's mysterious disappearance, Asha becomes convinced that Minke is hiding a dark secret. She puts a lot of pressure on Minke, which puts her in direct opposition to Lucas and Eva. Robert fears that Eva and Minke are in danger from Lucas, who is becoming increasingly unstable. Minke begins to doubt the Sphinx's mission and makes a radical decision.

Eva's astonishing discovery leads to more questions about Minke's disappearance. The Sphinx is forced to change her plans, while the doppelganger fights for her life. Meanwhile, detectives Asha and Fenna investigate Lena's family in Belgium and make an important discovery.

To unravel the mystery, Asha and Fenna must delve into both the Sphinx's and Lucas' pasts. In doing so, they discover that their lives are more connected than they expected. Lucas swears he's innocent, but is he really? The Sphinx prepares for an epic family reunion.
