for the facility. Meanwhile, Steinhoff and Tarek stay behind in order to prevent Berus from coming after them. Professor Thon reaches the facility and demands an explanation from Eckert, who accidentally injures him with a pistol. The fleeing prisoners are ambushed by the guards and trapped. Bosch, who could not keep up with the others, loses his sanity and kills Eckert with a fire extinguisher. Dora then escapes the room she was locked up in, and steals Eckert's gun. She injures one of the guards while he is engaged in fighting Tarek and Steinhoff, leaving only Berus to fight them. Tarek incapacitates Berus, who is nearly choked to death by Steinhoff until Tarek convinces him not to kill Berus. The film ends with a news break, confirming two deaths (Schütte and Eckert) and three severely injured (Thon, Berus, and Bosch). Both Berus and Thon will be put on trial, Berus for multiple homicides and torture with rape, and Thon for allowing an illegal and unethical experiment. In last scene Dora and Tarek are sitting together happily on the beach.
