Pawel Zawadzki is hired to go undercover in an elite high school in Poland, when three students mysteriously disappear.

Iwo shackles Tosia and Jaga to a radiator and steals their mobile phones. He then pulls out a gun and begins to fire.

People pay their respects to the victims of the massacre at the school and Pawel pays a visit to Karol in the hospital.

Pawel and Marta are desperate to be together, despite the fact that she is in danger. Meanwhile, Agata takes Karol home and starts to ask questions about rehearsals.

Pawel helps Ewelina get back on her feet and she agrees to help him in return by infiltrating the school; she will work as a waitress in the school cafeteria and use the name Wera.

Pawel tries to explain the situation with Ewelina to Marta, and Ewelina moves out to a youth hostel after the fight.

Radek, Borys, and Krzysztof inspect the scene of Ewelina's murder and Pawel cannot forgive Radek for his failure to protect her.

During a police interrogation Pawel discovers that Tymek is missing. He also deduces what the missing piece of Iwo's plan was.
