Tic, tac, Gock

A young man who asks for confidential information about a case to use it in the future. Time where he says is from. Maybe due the alcohol, maybe to feel important, Gock accepts; but things gets complicated when the case of adultery turns into a murder and in addition, Celedoni appears. Another man from the future, who accuses Nurtks of plot: Gock has to choose who to believe.
