Reta is sure that something terrible happened to Cody. She knows that experiments to create the Changed - modified soldiers, monsters who destroyed several cities in the past - have begun again. Will her brother become one of them? To save him, Reta is ready to do anything. To find him, she becomes a test subject for the Magenta project. Officially, this is just a test of new implants and methods of communication, and other participants in the experiment do not see any danger in this. Neither Cody, nor his friend Detlef, nor Erica, with whom he seems to be in love, nor Peter - the strange silent guy... And none of them look like a monster. Ryota also begins to doubt. Maybe she was just too scared of what she found in Vessem? But she knows for sure that until recently there were five test subjects.
