After the brutal murder of two fellow officers, Detective Thomas Berg grudgingly seeks help from the last person he wants: his ex-cop father, Alfred.

Another distress call at 1:15 a.m. sends an armed unit to a Stockholm suburb. The head of the police union issues Thomas a shocking ultimatum.

The result of a brazen move points to a troubling truth about the suspect. Thomas faces an ethical dilemma that could finally break the case.

Alfred embarks on a dangerous solo mission to prove a theory. Thomas steps further into a moral gray area to protect himself, his father and the case.

A gruesome discovery in the forest links back to a fateful night two years earlier. Can the killer be stopped before more police officers are murdered?
