Nine-year-old Nicole witnessed a murder. Because Nico's single mother Cora was dating a policeman, she entrusted her extremely troubled son to her friend Peter. But Nygu refused to talk because the victim begged him not to go to the police before he died. At first Cora and Peter wondered whether the little boy was telling the truth. But when the victim was found and was a colleague of Peter's police station, they believed that he was not making up a story. Officer Bach is in charge of the investigation. He had a very personal reason to find Nygu before he described what the murderer looked like. Because that person is Bach himself. When Bach almost killed Nico and Cora, they got Peter's help. He hid them in his father's house in the country. But shortly after they arrived, Cora found that Bach's men were looking for their mother and son. Did she trust someone she shouldn't?
