The game is based on real events.

In the late 1960s, California was engulfed in fear: a criminal with vague motives was brought to the region. He always acted prudently and left little or no evidence, and few witnesses saw his face clearly, making it very difficult to investigate. Moreover, the abuser wrote to the newspapers and criticized or praised the police depending on the progress of the investigation.

He made three attacks on young couples while dating away from people. The maniac used a pistol and a knife: sometimes at gunpoint, he forced the victims to tie each other up and put a cold weapon into action, sometimes shooting them right in the car. The motive for the crimes is unclear. There was practically no evidence, even though some of the victims survived and helped to make a sketch.
