In the winter of 2002, seven persons related to the old case were trapped in Blizzard Villa. The recorder announces the rules: every two hours the scene of the 1982 murder is restored, and if no lies are found, someone will die.
Interpol Lin Shen discovered that his mother Su Wan, who "committed suicide" twenty years ago, was actually the whistleblower of twin human experiments. And he himself was the "healthy control group" of the experiment.
When the survivor Lin Qian showed up to vote for trial, and when the microfilm in her mother's body was exposed, everyone understood: this death game was set up by Su Wan with her life.
