Colonel Vladimir, a military scientist, wants to conduct some secret experiments in Russia, but the Russian government does not accept this and does not give him the necessary permits. Colonel Vladimir prepares false documents in his home country and sets off for Turkey with his team. Vladimir equips a secret place with cells and medical equipment and starts looking for suitable subjects to conduct the sleep experiment he had planned all along. After a while, people started to disappear around the house where the colonel was staying. Vladimir put the people they kidnapped in the cell and started the 30-day sleep experiment with the scientists in his team. There was enough food, water and books for thirty days for the six people in the cell, as well as light to keep them awake and devices to release chemicals into the room. After the fifteenth day of the experiments, some changes began to appear in the subjects, they no longer spoke or reacted in the cell. When the guards try to enter the cell, another startling fact is revealed. The subjects are no longer human and the darkness that had been hidden inside them has taken over. Dark secrets have finally come to light, the problem is what to do with this truth.
