Tibor Malkáv is an ordinary 37-year-old man. Though not rich, he can buy whatever he needs. A few floors up in the hospital where he works lies his mother with cancer in her spinal cord. No matter how shallow their relationship is, Malkáv has no other relatives and he promises to not let her die. But the surgery can only be performed in Sweden and the costs are far beyond Malkáv's means. One day a one-eyed person introducing himself as the Cyclops turns up and makes him an offer: if Malkáv kills an unknown person, the Cyclops will provide the money for the surgery. Malkáv takes the job, which soon it turns out to be the greatest mistake of his life.
