Upon awakening in an underground cell with no memory of how they arrived there, four women fall victim to a menacing figure conducting a gruesome experiment. One by one the women are visited by the Surgeon, who carves a four-digit number into their skin indicating the exact time he will return to slaughter them. None of the women know why they have been selected to meet such a grim fate. Will they discover the secret behind this dark experiment in time to avoid a painful demise at the end of the Surgeon's sharpened blade, or is there truly no escape from his bloody den of torture and suffering?
